Overview of films through pneumatic single-seat single-seat pneumatic control valve regulating valve driven by the top structure, equipped with multi-spring actuator. With a compact, light weight, sensitive, fluid channel 3 streamlined, small pressure loss, valve capacity, flow characteristics of precision, and easy disassembly. Widely used for precise control of gases, liquids and other media, process parameters such as pressure, flow, temperature, liquid level is maintained at a given value. Particularly applicable to allow leakage around the valve pressure is not Star workplace. This series of products are standard type, adjust a variety of species off valves, bellows seal type, jacket insulation type.Nominal grade products have PN10,16,40,64; body diameter range of DN20 ~ 300. For fluid temperature from within the range of -196 Degree ~ + 560 Degree various grades. Leak star standards Class IV or VI level. Flow characteristics such as linear or equal percentage. Choose from a variety of different specifications.

Aerodynamic characteristics of single-seat control valve

1. driven by the top single-seat control valve, compact structure, less components, easy maintenance.

2. metal spool work for a variety of occasions, up to Class IV leakage standard, soft sealing structure spool of Class VI leakage standards.

3. Press the principles of fluid mechanics designed body and other low resistance flow channel cross section, rated flow coefficient increases by 30%. Adjustable range, inherent adjustable ratio of 50: 1. Multi-spring actuator structure, height reduced by 30 Percentage. Weight reduction of 30 Percentage.

4.ZJHPW type bellows seal valve, for moving the valve stem to form a complete seal, blocking absolutely fluid leakage. ZJHPJ type regulating valves with insulation jacket for easy to crystallize after the fluid cools, solidification clogging occasions.
