V230Y01/02 (B, K) Self-operated Pressure Regulating ValveOverview

V230Y01/02 (B, K) self-operated pressure regulating valve is an energy-saving control valve that realizes automatic pipeline pressure stabilization or relief by utilizing the energy of the regulated medium itself to balance with the spring force in the actuator, requiring no external energy sources. The valve operates on a self-feedback regulation principle, where the upstream or downstream pressure is introduced into the pressure-sensing diaphragm chamber of the actuator through a pressure-tapping pipe. The thrust generated by the medium pressure acts directly on the diaphragm and forms a dynamic force balance with the preset spring tension. The actuator drives the valve stem in a reciprocating motion according to changes in pressure deviation, real-time changing the flow area between the valve plug and seat to precisely control the fluid pressure drop. It is divided into the pressure reducing and stabilizing type (K-type, normally open) for controlling downstream pressure and the relief and back-pressure type (B-type, normally closed) for controlling upstream pressure. The sealing pair can adopt soft sealing or high-precision hard sealing technology to ensure excellent sealing integrity and adjustment accuracy under different temperature and pressure conditions. V230Y series self-operated pressure regulating valves feature simple structure, rapid response, wide setting range, and intrinsic explosion-proof safety. They are widely used for automatic constant pressure control of water, gas, steam, and oil media in petroleum, chemical, power, water supply and drainage, and urban heating systems.

V230Y01/02 (B, K) Self-operated Pressure Regulating ValveCharacteristic

1.Energy-saving self-operated drive:Requires no external energy such as electricity or air supply. It directly utilizes the pressure energy of the regulated medium to drive the actuator, saving energy and significantly reducing system automation costs.
2.Dual pressure regulation logic:Equipped with K-type (downstream pressure control) and B-type (upstream pressure control) forms to flexibly meet process requirements for pipeline pressure reduction or relief and back-pressure maintenance.
3.Pressure-balanced structure:The valve plug adopts a pressure-balanced design (such as balanced bellows, piston, or balancing holes) to effectively offset the unbalanced force generated by the pressure differential, allowing the valve to maintain high precision even under large pressure fluctuations.
4.Sensitive pressure-sensing feedback:The actuator is equipped with a large-area high-quality pressure-sensing diaphragm, which can precisely sense minute changes in pipeline pressure and rapidly feedback to the driving components, ensuring short dynamic response time and extremely high stabilization accuracy.
5.Convenient setting and adjustment:The valve is equipped with high-performance adjustment springs and nuts, allowing users to easily set target pressure values within a wide range by adjusting the spring preload. Field commissioning is intuitive and simple.
6.Durable and reliable materials:Valve bodies are available in various materials such as cast steel (WCB) or stainless steel (CF8/CF8M). Key seals and internals undergo precision machining and hardening treatments for erosion resistance and fatigue resistance, suitable for long-term continuous operation.
7.Intrinsic explosion-proof safety:The adjustment process is purely a mechanical physical action without any electrical signals involved. It possesses inherent safety attributes, particularly suitable for flammable, explosive, and harsh environments such as oil, natural gas, and chemical reagents.
8.Simple and economical maintenance:The overall structure is compact with minimal moving parts, resulting in a low failure rate. Components adopt a modular design, making disassembly, cleaning, and replacement of wearing parts possible without complex tools, significantly reducing downstream operation and maintenance expenses.
