Khps Electric High Pressure Cage Type Regulating Adjustable Valve

KHPS Electric High Pressure Cage Type Regulating Valve


The KHPS electric high pressure cage type regulating valve is a compact, efficient control device designed for precise flow regulation in high-pressure environments. Featuring an upper guiding structure, it ensures stability and reliability during operation. The valve is characterized by its small pressure loss, large flow capacity, and wide range of applications. Its spool design allows for good vibration resistance, making it suitable for demanding industrial processes. Equipped with a multi-spring diaphragm actuation mechanism, the KHPS valve offers a compact structure and significant output force, ensuring reliable performance under various conditions. It complies with GB/T 4213-92 standards and adheres to ANSI B16.104 leakage control standards. Valve Body

Cv Value and Stroke

1. If the actuator has an auxiliary gas source, choose the smaller supply pressure for calculating the allowable pressure difference.
2. The maximum allowable pressure difference must not exceed the value specified by ANSI B16.34.
3. When the valve is closed, the inlet pressure P1 must not exceed the allowable pressure difference.
4. The maximum allowable pressure difference varies depending on the valve leakage. For valves with leakage ≤ 0.01%, performance is ≤ 0.001%. Flange Distance (mm)
Shape Size (mm)

Note: The size of the H column in the table refers to the control valve without a handwheel. If a handwheel mechanism is used, the size of the handwheel mechanism should be adjusted accordingly.
