Shuttle Valves
The heart of a Pneu-Hydro shuttle valve is a stainless steel ball. The slightest pressure blows this ball from one O-ring seat to the other and directs flow to the outlet port. The breakaway friction of sliding seal designs is eliminated by this “contact seal” principle.
Pneu-Hydro shuttle valves are made from 316 stainless steel. Buna-N seals are standard, but Viton or other elastomers are available to meet specific requirements.
