Regulator assembly position
The outlet pressure can be set by means of the set-screw ; by turning clockwise this set-screw the pressure is increased and by turning it anti-clockwise the pressure is decreased.
The pipe fittings located upstream and downstream the regulator allow the reading of the relative pressures, passing from one family of gas to another, choosing the most suitable spring and adjusting the set-screw.
The stabilized pressure should be checked with a pressure gauge. After setting replace the upper cap .
Always be careful to follow the direction of gas flow indicated by the arrow on the regulator.
Suitable tools must be used for the regulator fitting on the inlet and outlet hubs. Never effect leverage on the sleeve of the upper cover when fitting the regulator.
For all models with the filter inside, the regulator is best fitted at a suitable height from the ground so as to facilitate the filter cleaning (always fit a suitable gas filter upstream the regulator).
Make sure that the pipes are clean and aligned so the regulator is not under stress. Do not remove the perforated diaphragm breather cap and do not obstruct the hole, otherwise the regulator will not work.
Install the regulator so it does not touch plastered walls. Make sure that the regulator is suitable to the intended use.
The regulator are completely maintenance-free. In the event of a breakdown, a general overhaul and factory testing is recommended.
To clean the filter simply remove the cover and replace the filter cartridge .
At every cleaning replace the gasket of the filter cover as well. After completing this operation check that there are no gas leaks through the cover itself.
ALL INSTALLATION AND MAINTENANCE OPERATIONS MUST BE CARRIED OUT SOLELY BY QUALIFIED PERSONNEL

Operational Schematic
Principle of Operation
When downstream demand decreases, the pressure under the diaphragm increases. This pressure overcomes the regulator setting (which is set by a spring). Through the action of the pusher post assembly, lever, and valve stem the valve disk moves closer to the orifice and reduces gas flow. If demand downstream increases, pressure under the diaphragm decreases. Spring force pushes the pusher post assembly downward and the valve disk moves away from the orifice.

Installation notice
Regulator operation within ratings does not preclude the possibility of damage from debris in the lines or from external sources. A regulator should be inspected for damage periodically and after any over-pressure condition. Key numbers referenced in this section are shown in above .
Ensure that the operating temperature capabilities listed in Specifications section are not exceeded.
1. Only personnel qualified through training and experience should install, operate, or maintain this regulator.
2. For a regulator that is shipped separately, make sure that there is no damage to or foreign material in the regulator.
3. Ensure that all tubing and piping have been blown free of foreign debris.
4. The regulator may be installed in any position as long as the flow through the body is in the direction indicated by the arrow cast on the body.
5. If continuous operation is required during inspection or maintenance, install a three-valve bypass around the regulator.
Adjustment
The range of allowable pressure settings is marked on the nameplate. If a pressure setting beyond this range is necessary, substitute the appropriate regulator control spring. Change the nameplate to indicate the new pressure range.
Refer to above for key number locations.
1. Remove the adjusting screw cap (part.36).
2. Loosen the lock nut (part.34).
3. Increase the outlet pressure setting by turning the adjusting screw (part.35) clockwise. Decrease the outlet pressure setting by turning the adjusting screw counterclockwise.
4. When the desired pressure is obtained, hold the adjusting screw (part.35) in place and tighten the lock nut (part.34).
WARNING
A regulator may vent some gas to the atmosphere. In hazardous or flammable gas service, vented gas may accumulate and cause personal injury, death, or property damage due to fire or explosion. Vent a regulator in hazardous gas service to a remote, safe location away from air intakes or any hazardous area. The vent line or stack opening must be protected against condensation or clogging.
Start up
To avoid personal injury or property damage due to explosion or damage to regulator or downstream components during start-up, release downstream-pressure to prevent an over-pressure condition on the diaphragm of the regulator.In order to avoid an over-pressure condition and possible equipment damage, pressure gauges should always be used to monitor pressures during start up.
1. Slowly open the upstream shut-off valve.
2. Slowly open the downstream shut-off valve.
3. Check all connections for leaks.
4. Make final control spring adjustments according to the adjustment procedures.
Shutdown
To avoid personal injury or property damage due to explosion or damage to regulator or downstream components during shutdown, release downstream pressure to prevent an over-pressure condition on the diaphragm of the regulator.
1. Close the nearest upstream shut-off valve.
2. Close the nearest downstream shut-off valve.
3. Open the vent valve between the regulator and the downstream shut-off valve nearest to it.
4. For a Type 627 regulator, the regulator will open to release pressure between the upstream shut-off valve and the regulator.

FLOW/PRESSURE LOSS CURVE
NSTALLATION REMARKS:
1.All installation/maintenance must be carried out by professionally qualified person. 2.Please close the gas supply valve before installation.
3.Gas filters are usually installed upstream of proprietary regulating and switching devices. After installation, the arrow direction on filter (3) must point to the using equipment and the filter should be installed anywhere that will not interfere with the normal operation of the equipment.
4.Care should be taken during installation to avoid debris or metal waste entering the filter.
5. For threaded connection, check and make sure the pipe thread is not too long; If the thread is too long, it will damage the filter when screws are installed. The connection of pipes and fittings must match the connection thread of the filter.
6.For flanged conncetion, check that the inlet and outlet butt flanges match each other. Avoid unnecessary mechanical pressure on the filter. At the same time, calculate the space needed to install the sealing ring. If the gap left after installing the sealing ring is too large, do not close the gap by tightening the filter.
7.Check the gas after installation to ensure no leakage.
Change the filter element if the difference between the up and downstream pressure exceeds 10 mbar. We recommend replacing it at least once a year anyways. To replace it, please follow the following procedure:
- Shut the gas inlet off by shutting the upstream valve off,
- Loosen the screws and remove the cover,
- Remove the filter element and clean it carefully or replace it with a new one
- Re-install the cover so that the guides inside
the cover correspond with the filter element, and retighten the screws,
- Check that there is no cover leak.

Installation notice
The CS400 Series regulators may be installed in any position. However, the spring case vent should be pointed downward. If the vented gas will be piped to another location, use obstruction-free tubing or piping at least equal in size to the vent and the end of the vent pipe must be protected from anything that might clog it.
Before installation, the pipe shall be purged to clean the impurities in the return stroke of the pipe, so as to prevent impurities from entering into the valve cavity and causing the voltage regulator can not work normally.
During installation, the air flow direction shall be the same as the arrow direction marked on the valve seat.
Pressure adjustment:
After the installation, screw down the plastic cover on the valve body, and then use a screwdriver to adjust the pressure spring cover inside, clockwise rotation, export pressure increases, counterclockwise rotation, export pressure decreases.
Maintenance
Regularly check whether the pipeline is blocked, and check the pressure gauge in front of the pressure reducing valve to ensure it is working normally etc.
To remove the dirt periodically . If there is problem with the regulator, please contact the manufacturer for feedback and support, and conduct for maintenance and testing if necessary. Use of a relief valve upstream or downstream of these regulators is recommended.
Warning!
All installation and maintenance operation must be carried out solely by qualified personnel!
GAS PRESSURE SWITCHES --APPLICATION
The gas pressure switch is used to detect the pressure of city gas, natural gas, LP gas or air etc. When the gas pressure changes, the diaphragm of the pressure receiving part detects it and operates the switch to ON/OFF control of the external electrical circuit. These switches are widely used to detect the upper limit or lower limit pressure of gas or air to be supplied to a gas burner, or to detect the clogging of the interlock filter of a burner blower.
