SI2 Series - Safety Valves

Product Type(s) : Relief Valves
Description :

Protection of tanks/vessels against excess pressure.

WHERE TO BUY

FEATURES

The spring-loaded full-stroke SI2 safety valve is approved for fluids and gases.

Advantages

  • Hygienic design
  • Ideally suited for CIP applications
  • All product-contact parts finished to Ra 0.8 m.
  • Pneumatic or manual operation
  • The pneumatic seat lifting device can be equipped with proximity switches for feedback signals.
  • Quick and easy seal replacement
  • The nameplate details uniquely identify each valve.

The SI2 safety valve prevents the allowed operating pressure from being exceeded by more than 10%. If, after opening, the adjusted response pressure falls below max. 10% (gases) and max. 20 % (liquids), the valve closes. Nominal dimensions: DN 25 DN 100. Product contact parts are made of stainless steel AISI 316L / 1.4404 (DIN EN 100888). In addition, the valve can be supplied with manual or pneumatic seat lifting device.

Key Applications

Field of application

The TÜV type-test approved valve is used at pressure vessels which have to be protected against excessive pressure. In the beverage and food industry as well as in pharmaceutical applications, the valve safeguards tanks and other containers against inadmissible excess pressure.
