Self-operated after-valve pressure control valve
self-operated after-valve pressure regulator is composed of the control valves, actuator and a spring used for pressure setting. It is suitable for controlling after-valve pressure in the pipes of non-corrosive liquids, gases and vapors. When the after-valve pressure rises, the control valve is closed.
The Self-operated After-Valve Pressure Control Valve is a state-of-the-art solution designed to maintain a constant, preset downstream pressure regardless of variations in the upstream pressure or flow rate. This highly reliable valve operates independently, without the need for an external power source, making it an energy-efficient choice for various industrial applications.
Crafted with high-quality stainless steel or carbon steel materials, this valve offers excellent durability and resistance against wear and tear, corrosion, and extreme temperatures, ensuring a long lifespan and reduced maintenance needs. Its self-operating nature eliminates the necessity for manual adjustments, leading to improved operational efficiency and safety.
The valve’s compact design allows for easy installation and integration into existing systems, while its precise control mechanism ensures optimal performance under varying conditions. Whether you’re managing a complex industrial process or a simple water supply system, the Self operated Pressure Valve is a convenient, cost-effective solution that delivers consistent, reliable results.
