How to use gas pressure reducing valve

Clockwise is pressurization, counterclockwise is decompression. After a few operations, you will know the strength of control.

1. Insert the valve inlet into the angle valve interface of the steel cylinder and tighten the handwheel counterclockwise. The pressure reducing valve should be kept in a horizontal position, the air pipe must be inserted into the warning line, and the air outlet hose should be fixed with a clip.

2. Before the product leaves the factory, the outlet flow and pressure have been adjusted. Don't adjust them without authorization.

3. After the product is used, the cylinder angle valve should be closed, so that the pressure reducing valve is not in working condition.

4. For the convenience of operation and maintenance, valves are generally installed vertically on horizontal pipes.

Installation requirements of pressure reducing valve

1. The installation of pressure reducing valve shall be carried out after the pressure test and flushing of water supply network are qualified.

2. Check the pressure reducing valve before installation: its specifications and models should be consistent with the design; The connector between the control pipeline outside the valve and the pilot valve should not be loose; The appearance should be free of mechanical damage, and foreign bodies in the valve should be removed.

3. The water flow direction of the pressure reducing valve should be consistent with that of the water supply network.

4. The filter should be installed at the inlet side, and the control valve should be installed at the front and rear.

5. The adjustable pressure reducing valve should be installed horizontally with the valve cover facing upwards.

6. Proportional pressure reducing valve should be installed vertically; When installed horizontally, the orifice of single breathing hole pressure reducing valve should be downward, and the orifice of double breathing hole pressure reducing valve should be horizontal.

7. When installing a pressure reducing valve without a pressure gauge, a pressure gauge should be installed in its front and rear adjacent parts.
