Special for seawaterSelf operated pressure regulating valveIt is an actuator product that does not require any external energy and utilizes the energy of the regulated medium to achieve automatic regulation. The product features the ability to work in places without electricity or gas, while also saving energy. The pressure setting can be adjusted freely during operation. With quick opening flow characteristics, sensitive action and good sealing performance, CONTROL ENGINEERING China has all rights reserved, so it is widely used in the automatic control of pressure reduction and stabilization of various gas, liquid and steam media (used for post valve regulation), or pressure relief and pressure holding (used for pre valve regulation) in various industrial equipment such as petroleum, chemical industry, electric power, metallurgy, food, light textile, machinery manufacturing and residential buildings. The attached condenser can be used at temperatures ≤ 350 ℃.

Usage method of seawater specific self operated pressure regulating valve　　
1. Operation when using gas or low viscosity liquid at room temperature:
(1) Slowly open the front and rear shut-off valves of the valve;
(2) Loosen the exhaust plug until gas or liquid overflows from the actuator
(3) Then tighten the exhaust plug again, and the regulating valve can work. The required pressure value can be obtained by adjusting the pressure regulating disc. When adjusting, pay attention to the pressure indication value, move slowly, and do not make the valve stem rotate along with it
2. Operation when using steam:
(1) Unscrew the drain screw from the condenser
(2) Loosen the exhaust plug of the actuator
(3) Add through the injection port using a leakage head until the exhaust hole flows out
(4) Tighten the exhaust plug and continue to inject water until it overflows from the injection port
(5) Tighten the injection port screw
(6) Slowly open the front and rear shut-off valves of the regulating valve
(7) Adjust the pressure regulating disc and observe the pressure reading until it reaches the required level.
