GZ810 Self Operated Single Seated Pressure Control Valve

GZ810 Self Operated Single Seated Pressure Control Valve is a kind of spring direct acting universal pressure regulating valve, which can be widely used in various types of low corrosion gas and low viscosity liquid. The choice of configuration can achieve upstream pressure control and downstream pressure control. The lowest control pressure is 3KPa, and the maximum control pressure is 3600KPa. The lowest temperature is -48 C, and the maximum use temperature is 300. 

Features

1, Safe overload---Safety is always the most important in any case. The media of self-regulating valve will directly go into the actuator, and when the system is over pressure, the valve will be severely damaged. The overload protection mechanism of the valve will carry the overload pressure safely which can be higher than the upper limit value of the pressure regulating range or even several times. In some configurations it can fully achieve nominal pressure.

2, Safe overload---Safety is always the most important in any case. The media of self-regulating valve will directly go into the actuator, and when the system is over pressure, the valve will be severely damaged. The overload protection mechanism of the valve will carry the overload pressure safely which can be higher than the upper limit value of the pressure regulating range or even several times. In some configurations it can fully achieve nominal pressure.

3, Reliable sealing--- The valve stem is a long ripple pipe structure, and is sealed with a sealing ring, so that the valve stem is provided with a reliable seal.

4,High accuracy--- Bellows stem friction is much lower than that of the traditional packing structure, and optimized design of spring and actuator will always find the best combination, so that the pressure valve has high control accuracy.

5,Low leakage--- Single seat valve has a low leakage when closed, and soft sealing valve can completely shut off the fluid to keep the pressure.


Benefits

1. Rotating the adjusting nut can set pressure adjustment directly. Due to eliminating a traditional pillar structure, adjustment can be easier and quicker.

2. There are a variety of actuator type, valve core structure and rubber material to be chosen for different media and temperature requirements.

3. Actuator, as an important part of the pressure regulating valve, is formed with the stainless steel sheet, and has a very high pressure endurance and long service life.

4.The determination principle of each structure of GZ810 pressure relief valve is to achieve the most convenient installation and maintenance on the premise of ensuring the performance index. The internal inspection and maintenance of the valve body can be carried out without removing the valve body or special tools. The principle of the valve cover center positioning eliminates all unnecessary duplication of cooperation, and enough space is left within the pieces, so that the inner parts can be easily removed or put into, even in the corrosive carbon steel valve.
