RWH-03

Handwheel Operated Brass Valves in Diaphragm Design for Speciality & Refrigerant Gases

RWH-03 design uses two-piece spindle separated by non-perforated diaphragms. Five diaphragms in series act as gland packing and prevent external leakage when the valve is in open condition. The replacement of elastomeric seals (as in O-ring seal design) with metal diaphragms gives the valve superior leak integrity to the atmosphere. The valve has no threads or lubricants in the gas stream. This prevents generation of particles and contamination of gas and makes the design ideal for use for refrigerant and high purity gases.
