Product Description
658 15T59411711T1 25601502 / 88378204
Description
The GEMÜ 658 2/2-way diaphragm valve has a two-stage actuator. In addition to full stroke, a partial stroke can be set via two pistons working independently of each other.All actuator parts including closing springs (except seals) are made from stainless steel. The valve is available with a Normally Closed control function. An opening stroke limiter for setting the partial stroke is integrated as standard.
Features
- An adjusting screw in the actuator enables the setting of the opening and closing function and also the setting of a partial stroke (for reduced flow)
- Both fast on/off operation and precision dosing of the working medium possible
- Suitable for inert, corrosive, liquid and gaseous media
- CIP/SIP capable
- Compact design (ideal when space is at a premium)
- Version according to ATEX on request
- Mounting of proximity switches for OPEN and CLOSED position feedback possible (MG 25 – 50)
