Safety Valves – Series 140

ASME SECTION VIII FOR AIR-GAS

Our Series 140 is designed for heavy-duty applications where a compact valve is required. It offers excellent seating characteristics with fast-action reseating, minimizing medium loss and improving energy efficiency. Built to endure rugged industrial conditions, these valves provide high-capacity flow rates for air and inert gases.

Usages
