Features

  • Steepest Interior Surfaces - Designed to completely drain without puddling, even in significantly sloped lines.
  • Stainless Steel Body - Body material is 316L Stainless Steel with 20 µ in. Ra internal and 32 µ in. Ra external. Electropolish option available.
  • Self-Centering Valve - Leak-tight shut off. Assembly of actuator and valve to impingement plate allows the valve to self align with center of the orifice.
  • Temperature-Sensitive Actuator - One moving part. 316L Stainless Steel, fail open, welded actuator for maximum corrosion, thermal and hydraulic shock resistance.
  • Directional Discharge - Erosion prevented by directing discharge to center of piping.
  • Maintenance - Can be easily removed and disassembled for sterilization or repair.
  • Industry Standard Food Grade Gasket - White Viton food grade gasket offers superior performance for higher pressure steam applications.
  • Large Orifice Selection (ST600) - Broad selection of orifice sizes provides greatest sizing and selection flexibility.
  • Superior Air Handling - Best air handling capability provides for fast startup.
  • Unique SLR Orifice Option - Provides drainage at saturated temperatures, instant reaction to load changes and guaranteed fail-open operation for extra critical operations.
  • Bar Stock - Connection fittings are not welded onto inlet and outlet pieces.
  • Universally Configurable (ST800) - Horizontal connections from any direction on standard model; HV and VH models feature one multi‑directional horizontal and one vertical connection.
