The Ruelco ‘SV-1’ double check valve is designed to act as a dual port non-return valve. Flow enters from both inlet ports on each side of the valve. Only the inlet with the higher pressure may flow through to the outlet port. The 17-4 stainless steel construction allows for high corrosion resistance in harsh environments. The SV-1 was designed with a high flow rate in mind with the orifice being equal to 1 /4″
I.D. tubing. The SV-1 can be disassembled and repaired without the need for special tools.

• Stainless Steel construction (N.A.C.E. Model available).
• All soft seal design.
• Large C_v factors produce large flow rates.
• Small compact design.
