The HPC high-pressure cage-type control valve is a pressure-balanced control valve. The fluid channel of the valve body is in an S-shaped streamline design, featuring small pressure drop loss, large flow rate, and a wide adjustable range. Equipped with a multi-spring diaphragm actuator, the valve has a compact structure and large output force. It is widely applicable to high-pressure drop occasions requiring good dynamic stability, low noise, and little cavitation corrosion.

Equipped with HA or VA actuator broussonetia papyrifera (with positioner) See Table 2, 3
Air-to-close valve Table 2

Notes: 1. The numbers in the dark-colored boxes indicate the standard specifications for valve actuators—Broussonetia papyrifera.
2. The allowable pressure difference condition when the valve is closed is ΔP=P1 (P2=0), and the pressure difference at full closure varies slightly with different outlet pressures P2.
3. The maximum allowable pressure difference must not exceed the maximum value specified in ANSI B16.34 or JIS B2201.
4. The inlet pressure P1 must not exceed the allowable pressure difference when closed.
5. In the same cell, the upper number indicates the allowable pressure difference when the valve is fully open, and the lower number indicates the allowable pressure difference when fully closed.

Notes: 1. If the actuator broussonetia papyrifera is equipped with an auxiliary air source, the smaller of the two supply pressures should be selected as the basis for calculating the allowable pressure difference.
2. The condition for the allowable pressure difference when the valve is closed on the table is △P=P1 (P2=0). The pressure difference when fully closed varies slightly with different outlet pressures P2.
3. The maximum allowable pressure difference must not exceed the maximum value specified in ANSI B16.34 or JIS B2201.
4. The inlet pressure P1 must not exceed the allowable pressure difference when closed.
5. In the same cell, the upper number indicates the allowable pressure difference when the valve is fully open, and the lower number indicates the allowable pressure difference when fully closed.
