Features

Advantages

  • Product passages are smooth and the special seals ensure thorough cleaning.
  • Unique metallic stop prevents the valve flanges from being tightened too much and protects the valve seal from mechanical over-stress thus improving seal lifetime.
  • One actuator covers all diameters from 1″ (25 mm) - 4″ (100 mm).
  • Slide bearings on the pivots of the discs increase operating reliability.
  • Visual indication of open/closed position.
  • SVS1F intermediate flange design allows simple removal and easy access of valves that are in lengthy or fixed pipelines.
  • ATEX compliant models
  • Designs with electro-pneumatic control (flow control) with Bürkert positioner

SV1 valves are available from DN 25 DN 150, 1 4.

SVS1F valves are available from DN 25 to DN 250, 1” – 6” OD, 2”- 6” Sch5



    
Theory of Operation

How does an SV / SVS series butterfly valve work ?


A butterfly valve is used within a processing line and can be in two states.  The open state allows flow and the closed state shuts-off flow in the line.  The valve opens and closes by turning a disc 90° which can be performed manually or remotely using a pneumatic actuator.  The pneumatic actuator opens the disc by way of compressed air and closes the disc by spring force.
