Single seat regulating valve

• 

Single-seat regulating valve is a top-guiding structure of regulating valve. Its body fluid passage …

A brief introduction:
HTS seriesSingle seat control valveIs a top guide structure regulating valve, the valve fluid channel was streamlined S, the pressure drop, flow rate, wide adjustable range and high precision valve flow characteristic curve, oriented area, good vibration resistance.The valve is equipped with multi spring diaphragm actuator, compact structure, large output force.Can be used to control various fluid pressure and temperature.

Six, value and travel:

Note: 1, symbols, and delta said valve specifications.2, the symbol said the flow characteristic of the valve according to the standard of IEC 534-2.
Seven, allow pressure:
1. The plunger valve, metal seat (%CF, LCF) A. gas - off valve 100KPa

B. gas valve open

Note: 1. does not exceed the maximum allowable pressure of ANSI B16.34 or JIS B2201 standard maximum working pressure.
Figure 2. the same box above said valve is normally open to allow pressure, under the digital representation allows the differential pressure valve is fully closed when the.
Allow pressure 3. with *, valve control liquid, allowing the pressure is only 3MPa, more than 3MPa, please use the LHLC valve.
4. ash bottom box number indicates valve equipped with standard actuator.
