ANSI GB Standard Cast Steel Self Operated Pressure Regulatng Valve
Product introduction:
Control valves, also known as regulating valves, are used to regulate process parameters such as medium flow rate, pressure, temperature, and liquid level in the field of industrial automation process control. According to the control signals in the automation system, the valve opening is automatically adjusted to achieve the adjustment of medium flow rate, pressure, temperature, and liquid level. It is an important component of fluid input systems and industrial process automation
ZZYP series self-operated pressure regulating valve (pressure reducing valve) does not need any additional energy, the use of the medium's own energy to achieve automatic regulation of the actuator product, the biggest feature of the product is that it can work in no electricity, no air, while saving energy, the pressure setting value can be adjusted at will in the operation, the use of fast-opening flow characteristics, sensitive action, good sealing performance, therefore, it is widely used in petroleum, chemical, electric power, metallurgy, food, textile, machinery manufacturing and residential buildings and other industrial equipment with gas, liquid and steam medium decompression and pressure regulation (for pressure regulation after the valve), or pressure relief and pressure regulation (for pressure regulation before the valve) automatic control.

Product features:
- The self-operated pressure regulating valve does not require external energy and can work in places without electricity or gas, which is convenient to use and saves energy.
- The pressure segmentation range is fine and intersects with each other, with high adjustment accuracy.
- The pressure setting value can be continuously set during operation.
- Pressure adjustment back of the valve can be with a ratio of 10:1 to 10:8 between the pressure front and back the valve.
- Rubber diaphragm type detection, with high detection accuracy and sensitive action of the actuator.
- Adopting a pressure balancing mechanism to make the regulating valve responsive and precise in control.
