Product introduction:
Pressure reducing valve is generally divided into diaphragm type and piston type，nominal diameter≤DN500 is diaphragm type，more than DN600 type is piston，both working principle is similar，this is valve by the main valve 2, pilot valve 1, needle valve 5, ball valve 3 and a pressure gauge4.Pressure reducing valve main control of the main valveof the fixed outlet pressure， the main valve outlet pressure does not change due to changes in the inlet pressure, apply to industrial water supply, water, fire water supply and water pipeline system for domestic use.
Product advantages:
1.The main valve outlet pressure does not change due to changes in the inlet pressure. 2.Not due to the changes in the downstream water consumption of the main valve to change its export pressure. 3.Wide pressure regulating range，easy to adjust.
Selection basis：

Installation requirements
1.The installation of the pressure reducing valve should be carried out after the pressure test and flushing of the water supply pipe network are qualified;
2.Each connection position of the pressure reducing valve should be carefully checked before installation;
3.The water flow direction of the pressure reducing valve should be consistent with the water flow of the water supply pipe network;
4.The adjustable pressure reducing valve should be installed horizontally, and the bonnet should be upward;
5.The proportional pressure reducing valve should be installed vertically;
6.When installing a pressure reducing valve without a pressure gauge, a pressure gauge should be installed at the front and rear adjacent parts.
