Single seat and change-over valves DELTA SW4 have been
developed for use in the brewing and beverage, dairy
and food industries as well as for chemical and pharmaceutical
applications.
The valves are designed for universal applications and stand out
for their increased mechanical reliability and absolute ease of
service.
The field of application of the DELTA SW4 - valve is to shut off
and to change over line sections.
- Operation by pneumatic actuator with air connection,
reset by spring force.
- By different assembly of the actuator, the following designs
are possible:
NC: actuator normally closed / air-to-raise, spring-to-lower
NO: actuator normally open / air-to-lower, spring-to-raise
- The inner parts of the actuator need not be serviced.
- The cleaning of the inner valve is undertaken during CIP cleaning
of the line system.
- The standard SW4 valve is equipped with a control unit
DELTA CU 41 Direct Connect.
- The luminous diodes in the control unit indicate the position
of the valve shaft.
