Self-Closing Sample Valves

 

Self-closing Sampling Valves are designed to allow safe and quick sampling of volatile liquids under pressure on process lines, storage tanks or pressure vessels. Depressing the manual lever releases a spring-assisted plunger to draw off liquid. Releasing the lever reseats the Viton or Teflon seal against the valves machined seating surface. Standard sampling valves are 316 stainless steel. Flow reducers available upon request.
