The SV-20 is a direct acting, diaphragm valve designed to handle corrosive and high purity
fluids. The Fluoropolymer body construction provides outstanding chemical resistance and
compatibility to a wide range of fluids.
The diaphragm design isolates fluid from the solenoid and all other operating parts.
Wetted surfaces are made from either fluoropolymer or perfluoroelastomer. All valves
provide tight shutoff and bubble tight sealing when used with air or liquid. No minimum
pressure is required for operation or sealing.
The compact size (2.5" high x 1" diameter) and low weight (less than 5 ounces)
make them extremely suitable for use in biological, medical, and chemical instrumentation
equipment.
All SV-20 valves have a low internal volume of only .098 cc. Ports are flat bottom type
and accept 1/4"-28 treaded low dead volume fittings. This provides a bubble tight
seal which prevents excessive fluid from remaining between the fittings and the valve
cavity.
Electrical Data.
SV-20 valves provide quiet instrumentation operation for both AC and DC service. All
valves have continuous duty coils wrapped with polyimide tape, with 15" fluoropolymer
leads per UL Class 180. AC solenoids employ rectified coils. Lower power ratings are
available for specific applications.
