This valve combines the function of a reverse flow pressure relief valve in parallel with that of a check valve with free flow in the forward direction – all into 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. The 281 PRI/Check Valve is available with or without integral safety screens in a range of 15 different relief flow cracking pressures for system pressures up to 5000 psi.
