Khps Electric High Pressure Cage Type Regulating Adjusting Valve

KHPS Electric High Pressure Cage Type Regulating Valve


The KHPS electric high pressure cage type regulating valve is a sophisticated control device designed for industrial applications. It features an upper guiding structure, which ensures precise and stable operation. The valve is compact in design, offering minimal pressure loss, high flow capacity, and a wide range of adjustability. Its spool design provides excellent vibration resistance, making it suitable for demanding environments. This leakage control valve complies with the ANSI B16.104 standard, ensuring reliable performance and safety. Equipped with a multi-spring diaphragm actuation mechanism, the valve delivers strong output force and a compact structure, meeting the GB/T 4213-92 standard. 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 should not exceed the maximum value specified by ANSI B16.34 standard.
3. When the valve is closed, the inlet pressure P1 must not exceed the maximum allowable pressure difference.
4. The maximum allowable pressure difference varies depending on the valve leakage. For valves with leakage ≤ 0.01%, the performance is less than or equal to 0.001%. Flange Distance mm
Shape Size mm

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