The Lee 0.375 inch PRI/Chek Valves combine the function of a reverse flow pressure relief valve in parallel with the function of a check valve with free flow in the forward direction into one easy to install insert. The relief valve function features a rugged Tungsten Carbide ball and a 440C seat for durability and long life. The remaining components are constructed entirely of stainless steel. The valves are available in a range of relief flow cracking pressures for system pressures up to 5,000 psi. The 375 PRI/Chek Valve has a maximum restriction of 220 Lohms in the free flow direction and is available in 7 different standard relief flow cracking pressures up to 5400 psid.

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.
