Single Seat Valves

Description

The SW4 Series single seat valve is a hygienic and highly adaptable solution designed to meet the rigorous standards of modern processing industries. Engineered for durability and cleanability, it is ideal for use in the dairy, food, beverage, brewing, and chemical sectors.

Key Features & Advantages

  • Manual or pneumatic actuation for integration into various process systems

  • Smooth product passageways with specially designed seals to ensure full CIP/SIP cleanability

  • Metallic travel stop prevents over-tightening, protecting seals from stress and extending seal life

  • Universal actuator: one actuator fits all sizes from 1″ to 4″ (25–100 mm)

  • Slide bearings on disc pivots for improved operating reliability

  • Visual position indicator shows open/closed valve status at a glance

  • SVS1F intermediate flange design allows quick valve removal and easy access, even in long or fixed pipelines

  • Compact construction ideal for installations with space constraints

  • ATEX-compliant versions available for use in explosive environments

  • Optional electro-pneumatic control with Bürkert positioner for automated flow control

  • Simple installation and servicing to reduce downtime and operating costs

Sizing Range

  • SV1 Valves: DN 25 to DN 150 / 1″ to 4″

  • SVS1F Valves: DN 25 to DN 250 / 1″ to 6″ OD, 2″ to 6″ Sch5

Operating Principle of SV / SVS Valves

The SV / SVS series valves are butterfly shut-off devices designed to control the flow of liquids in processing pipelines. They operate in two positions:

  • Open – allows free flow of the product

  • Closed – completely blocks the flow

Switching between these positions is done by rotating the disc 90°:

  • In the manual version, the operator turns a handle.

  • In the pneumatic version, the disc opens using compressed air and closes via the force of an internal spring.

This makes the valve a simple and reliable solution for a wide range of hygienic and industrial processes.

Key Application Areas

  • Dairy Industry – milk, cream, whey

  • Beverage Sector – juices, water, soft drinks

  • Brewing – wort, water, auxiliary liquids

  • CIP Systems (Clean-in-Place) – automated equipment cleaning

  • Cosmetics & Personal Care – creams, shampoos, soaps

  • Chemical Industry – non-aggressive process fluids
