Overview of 35-35212 35-35222 70-35002 Pneumatic eccentric rotary valve

35-35212 35-35222 70-35002 Pneumatic eccentric rotary valve are two types of pneumatic actuators, Type 35 spring return drum diaphragm actuator (hereinafter referred to as drum diaphragm actuator). Type 70 two-way acting piston actuator (piston actuator for short). The structure of eccentric rotation is relatively novel. The valve body is approximately cylindrical. An eccentric distance is designed between the center of the valve core spherical surface and the rotation center of the valve shaft. When the valve shaft drives the valve core to rotate, the valve core spherical surface rotates eccentrically relative to the center of the valve body

Working Principle of 35-35212 35-35222 70-35002 Pneumatic eccentric rotary 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
