Dual-Function Valve

p-theleecoThe 281 PRI/Chek Valve combines the function of a pressure-relief valve with a check valve in 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. Offered with or without integral safety screens, the valve is available in a range of relief flow cracking pressures for system pressures up to 5,000 psi. Maximum restriction in the free-flow direction is only 300 Lohms (550 Lohms for the screened version).
