Butterfly Valve
DELTA SVS1F DN125-250
Operating Manual rev.2
Use of high-quality stainless steel and seal material to the specified
requirements, the butterfly valve range DELTA SVS1F is applicable
in the food and beverage industries as well as in the chemical and
pharmaceutical industries.
The function of the butterfly valve is to shut off line sections.
Valves of the series DELTA SVS1F can either be operated manually
or remote controlled via a pneumatic actuator. Manual operation
and pneumatic actuator including add-on pieces are inter-
changeable.
Actuation by pneumatic actuator.
Reset by spring force into the limit position closed.
Extension of operating time of actuated valves by pneumatic air
throttle or adjusting screw in the control unit CU3 to optimize the
flow behaviour.
The butterfly valve can also be used in vacuum systems.
The valve opens and closes by turning the disc by 90°. Manual
actuation provides for locking of the disc in partly open position.
Smooth valve passage without diversion of line flow.
The opening diameter complies with the size of the inner line
diameter.
Cleaning of the product wetted valve surface is performed during
cleaning of the pipeline.
4. Auxiliary Equipment
Valve position indication - valve with pneumatic actuator:
Proximity switches to signal the limit position of the valve disc
can be installed in the yoke area if required.
We recommend to use our APV standard proximity switches.
Type:
three-wire proximity switch (ref.-No. 08-60-011/93)
Operating distance: 4mm / diameter: 11mm / length: 30 mm.
Feedback complete with support and proximity switch
(ref.-No. 15-33-023/93) for a limit position.
Using a valve position indicator other than APV, we cannot accept
any liability for faulty function.
