Excellent quality Pneumatic Spring Return Control Valve - Pneumatic small flow control valve for dropping reaction processing – Hoyee
Excellent quality Pneumatic Spring Return Control Valve - Pneumatic small flow control valve for dropping reaction processing – Hoyee Detail:
Small flow pneumatic control valve is designed for micro flow medium .The compact body ofLow flow pneumatic control valve has an S-shape flow passage that features low pressure loss, allows a large flowcapacity,rangeability, and high accuracy flow characteristics.
Small flow pneumatic control valve plugs are available in wide range of Cv values. The flow shut-off performance complies with the IEC or JIS standards. The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator leaded with multiple springs.
Small flow pneumatic control valve is widely applicable for reliable control of small flows in high or low temperature, high pressure process lines.
Feature：
1. Top -bottom guided double seat control valve valve seat, good stability
2. The pneumatic linear actuator consists of a diaphragm housing
3. Large adjustable range, Inherent adjustable ratio 50
4.With Insulation jacket
5.control valve type: Single-seated type ,Sleeve type, double-seat type, 3-way type.
6.Actuator Accessories
- Top-fitted handwheel for emergency operation
- Positioner
- Limit switches
