overview

70-35002 70-35112 70-35122 70-35212 70-35222 Pneumatic eccentric rotary control valve is composed of a pneumatic actuator and an eccentric rotary valve. There are two forms of pneumatic actuators:

The 35-type spring return rolling diaphragm actuator and the 70-type double-acting piston actuator, the eccentric rotary valve has a novel structure, the valve body is approximately a cylinder, and the center of the spool spherical surface and the rotation center of the valve stem are designed with a Eccentricity: When the valve stem drives the valve core to rotate, the spherical surface of the valve core rotates eccentrically with respect to the center of the valve body, and its trajectory is a wheel-shaped curve. When the valve is closed, the flexible arm of the valve core is elastically deformed, so that the spherical surface of the valve core and the valve seat are closely attached to achieve a reliable seal, so the valve is also called a cam flex valve.

Features

70-35002 70-35112 70-35122 70-35212 70-35222 Pneumatic eccentric rotary control valve

1. Good sealing

2. Has a larger rated flow coefficient

3. High dynamic stability in two flow directions

4. Wide applicable temperature range

5. Compact structure, light weight, and easy to install

6. The valve body has a simple flow path and is suitable for fluid media with high viscosity. The valve trim or valve body can be applied to granular media by coating cemented carbide.

7. It can be manufactured into a jacketed eccentric rotary regulating valve with a heat medium jacket
