The Solenoid Operated Pneumatic Isolation Valve is the optimal solution when a tight seal is needed over a wide range of pressures. Its robust design has been tested using proven methods, including endurance testing up to 100,000 cycles, temperature shock, thermal cycling, and more. With a weight as low as 0.14 of a pound, this valve delivers reliable performance in the smallest package size. The design draws upon on MultiSeal® technology to radically simplify port layout and provide significant space and weight savings.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
