Overview of  97-21000W 97-21200W 97-21120W 97-21125W Pneumatic cage guided control valve

97-21000W 97-21200W 97-21120W 97-21125W Pneumatic cage guided control valve is a product developed on the basis of digesting and absorbing foreign advanced technology. 97-21000w series products are composed of pneumatic diaphragm multi spring actuator and 21000w series single seat bellows sealing valve, with small volume and light weight.

Working Principle of 97-21000W 97-21200W 97-21120W 97-21125W Pneumatic cage guided control valve

The regulating valve is composed of electric actuator or pneumatic actuator and regulating valve. The regulating valve is usually divided into straight through single seat regulating valve and straight through double seat regulating valve. The latter has the characteristics of large flow capacity, small imbalance and stable operation, so it is usually especially suitable for occasions with large flow, high pressure drop and less leakage .The regulating valve is used to regulate the flow, pressure and liquid level of the medium. The opening of the valve is automatically controlled according to the signal of the regulating part, so as to achieve the regulation of medium flow, pressure  and liquid level. The regulating valve is divided into electric regulating valve, pneumatic regulating valve and hydraulic regulating valve.
