Single seat control valve
2 year ago
Product Description:
Pneumatic single-seat control valve is composed of valve body, valve seat, valve core, actuator, etc. The valve body is usually made of cast iron, stainless steel and other materials, with good corrosion resistance and sealing properties. The valve seat and valve core are usually made of wear-resistant and high-temperature-resistant materials to ensure the reliability and service life of the valve. The actuator usually uses a pneumatic device to drive the movement of the valve core through compressed air or gas to achieve fluid regulation and control.
Description Features:
1. High-precision adjustment: Pneumatic single-seat control valve adopts precision valve core design and pneumatic actuator, which can achieve precise flow and pressure adjustment and is suitable for occasions with high fluid flow and pressure requirements.
2. Fast response: The pneumatic single-seat regulating valve has a fast response speed and can quickly adjust the valve opening to meet the changing requirements of fluid flow and pressure.
3. Strong corrosion resistance: The valve body, valve seat and valve core are made of corrosion-resistant materials, which can operate stably in corrosive media for a long time and are suitable for chemical, petroleum, electric power and other industries.
