Specification: Material:Brass;  Size:1/2"(DN15), 3/4"(DN20), 1"(DN25), 1-1/4"(DN32);  Connector Type:G Thread Female;  Nominal Pressure:1.6MPa (PN16);  Feature: - 4 Sizes, Pressure Reducing Valve: The Pressure Reducing Valve is of high precision, and quick respond. Standard DN20(3/4 inch) thread is convenient for you to use;  - Wide Application: This pressure reducing is is marked with water inlet direction, compact structure and small size. Applicable to hydraulic instability, water flow too fast, water purifier, solar energy, gas heater, faucet, etc;  - Strong Practicability: This pressure regulator adopts the piston structure, suitable for various kinds of environmental conditions. Easy to connect with the tube, simple to use and strong practicability;  - Premium Quality Brass: 100% brand new and high quality brass pressure reducing valve, made of high quality brass, wear-resistant, not easy to rust, strong and durable;  - Valve working principle can be simply understood as the entrance pressure and outlet pressure = spring force, through the control valve closure flow inside the opening of the size to control the pressure at the outlet, the liquid through the opening, closure and fluid resistance is small, the pressure loss is small, the outlet pressure is greater, and vice versa outlet pressure is small;  Package Include: 1*Water Pressure Reducing Valve;  1*Pressure Guage
