SLV5 Chemical Air Operated Emergency Valve

The Liquip SLV5-AROC Chemical Trim (FFKM) Valve leads the industry with its low profile, low splash and vortex free design which minimises static and also enables faster tanker unloading than traditional mushroom poppet valves. It is used globally by road tankers and has become a benchmark for the industry.

FFKM (a perfluroelastomer commonly known as Ekraz or Kalrez) is one of the most chemically resistant materials
available and is suitable for some of the harshest chemical compounds. FFKM is commonly used with aggressive,
corrosive and reactive chemicals.

  • Incorporates the latest technical advancements to ensure fast and safe loading and discharge of road tankers.
  • The valve is installed underneath the compartment floor and controls the flow of product from each compartment individually.
  • The 125mm dia poppet has a concave design which operates as a deflector reducing splash, surge and static build up during loading and similarly during discharge.
  • Hinged poppet design gives minimum height, so valve requires very little clearance to drop out for servicing.
  • Emergency jacking screw in the air ram allows drainage if air is unavailable.
  • Can be used with top operator.
  • FFKM seals can be distinguished by the white colour.
