Win the battle against gravity and vacuum siphoning the easy way. These check valves offer safety with full flow rates. Custom made with 100% methanol resistant stainless spring, brass snap ring, and EPDM seals for no corrosion even with high methanol concentrations. Features a 5PSI cracking pressure, 3000cc/min flow capacity, 1/8" NPT ports, and 1/4" compression fittings (or 3/16" by special request in order notes).
For a more compact setup, consider our CHECK TEE with integrated control valve. More sophisticated control options will call for a flow control solenoid.
