ZHPC High pressure cage control valve

ZHPC High pressure cage control valve

Detailed

ZHPC high pressure cage regulator is one of Cv3000 series products. It can control high pressure fluids at different temperatures. It is a pressure balancing regulator. It is widely used in high pressure drop situations requiring good dynamic stability, low noise and low cavitation corrosion.

main features

Equipped with multi spring film actuators, compact structure and high output power.

Valve structure is compact, fluid channel is S streamlined, pressure drop loss is small, flow rate is large, adjustable range is wide。

Control valve leakage meets ANSI B16.104 standard.

Typical flow characteristic curves 

 

Allowable pressure difference

I. LHA or LVA actuators for valves

A. gas shut valve 100kPa


 

B. gas open valve 100kPa

 

Note: P=P1(P2=0) is the condition of allowable pressure difference when the table is closed. The pressure difference at full closure varies slightly with the outlet pressure P2.

Maximum allowable differential pressure shall not exceed the maximum working pressure specified in ANSI B16.34-1981 or JIS B2201-1984 standards

The inlet pressure P1 shall not exceed the allowable pressure difference when the valve is closed.

* the number above the same grid indicates the allowable pressure difference, and the lower figure indicates the allowable pressure difference.

II. Valve equipped with LVP actuator 100kPa



Note: If the actuator has an auxiliary gas source, the smaller one of the two should be selected as the basis for calculating the allowable pressure difference。

The condition of allowable pressure difference is P=P1 (P2=0) when the table is closed。 The pressure difference at full shutdown varies slightly with the outlet pressure P2。

Maximum allowable differential pressure shall not exceed the maximum working pressure specified in ANSI B16。34-1981 or JIS B2201-1984 standards

The inlet pressure P1 shall not exceed the maximum allowable pressure difference when the valve is closed.

* the number above the same grid indicates the allowable pressure difference, and the lower figure indicates the allowable pressure difference.
