HIGH QUALITY: The water pressure reducing valve is made of brass, durable and easy to install. Suitable for cold water and hot water GOOD FUNCTIONALITY: This pressure reducing valve adopts piston structure, simple internal structure, strong environmental use , durable to use. CONVENIENCE: The water pressure regulator can reduce the water pressure and also make it stable. Easy to adjust, simply adjust the brass screw (at the top on the regulator) to change the pressure - or + EASY TO USE: Compact size for easy use, the removable valve spool for easy cleaning or replacement when needed by removing it. APPLICATION: Hydraulic instability, water flow too fast, water purifiers, solar energy, gas heater and faucet . Technical characteristics: Material: brass. Maximum load: 16 kg/cm. Maximum book dimensions: 0.05 0.8 MPa (7.25 116 psi). Connector Size: DN20 Inlet Pressure: 1.6 Mpa (Max) / 232 PSI . Weight: 425 g. Package contents: < /p> 1 pressure gauge. 1 brass water pressure reducing valve. Note: The water flow direction of the valve body installation should be strictly consistent with the direction marked on the valve. If the direction is wrong, the water pressure gauge will not be indicated. After installation, adjust the valve to an adequate pressure range to avoid excessive pressure damaging the pressure gauge or the pressure gauge not working if the pressure is too low.
