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.
