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 control valve designed with an upper guiding structure. This design ensures a compact and efficient system, featuring low pressure loss, large flow capacity, and a wide range of applications. The spool is oriented in a way that minimizes vibration, making it ideal for precise control. It meets the ANSI B16.104 standard for leakage control and is equipped with a multi-spring diaphragm actuation mechanism, offering a compact structure and significant output force. The product complies with GB/T 4213-92 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. The inlet pressure P1 must not exceed the maximum allowable pressure difference when the valve is closed.
4. The maximum allowable pressure difference varies with different valve leakage. For valves with leakage ≤ 0.01%, performance is ≤ 0.001%. Flange Distance (mm)
Shape Size (mm)

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