P627 High Flow Gas Regulator • • • • Wide Range of Flow Capacities Durable Powder Coated Exterior Installation Versatility NACE Construction Available The P627 is a spring loaded, direct-operated regulator for both low and high pressure applications in the oil and gas industries. These regulators provide durability, from the powder-coated epoxy exterior finish, as well as installation versatility, from the multi-position body and spring case configurations. These regulators are also available in an external pressure registration model (P627M), and NACE construction.
