Body/Bonnet: Ductile Iron (epoxy coated), Carbon Steel (epoxy coated), Stainless Steel, Aluminum Seat Ring: Stainless Steel, Bronze Stem: Stainless Steel, Monel Spring: Stainless Steel Diaphragm: Buna-N, Viton, (Nylon reinforced) Seat Disc: Buna-N, Viton Pilot: Stainless Steel, Bronze Other pilot system components: Stainless Steel, Bronze/Brass Tubing & Fittings: Stainless Steel, Copper/Brass SOLENOID Enclosure: Explosion Proof NEMA 4X, 6P, 7, 9 Body: Stainless Steel, Brass Voltages: 24, 120, 240, 480 VAC 12, 24 VDC Note: Working pressures of solenoids vary greatly, consult factory on application of OCV Model 127-9 valves. The two-stage preset valve shall open in one stage and close in two stages based on signals from the preset register. While open, the valve shall control the downstream pressure to the adjustable setpoint, regardless of fluctuations in upstream pressure. DESIGN The two-stage preset valve shall be a single-seated, line pressure operated, diaphragm actuated, pilot controlled globe valve. The valve shall seal by means of a corrosion-resistant seat and a resilient, rectangular seat disc. These, and other parts, shall be replaceable without removing the valve from the line. The stem of the main valve shall be guided top and bottom by integral bushings. Alignment of the body, bonnet and diaphragm assembly shall be by precision dowel pins. The diaphragm shall not be used as a seating surface, nor shall the pistons be used as an operating means. The orifice plate shall be integrallyinstalled in the valve inlet flange. The pilot system shall be furnished complete and installed on the main valve. It shall include two solenoid pilots, a needle valve and an inline strainer. The two-stage preset valve shall be operationally and hydrostatically tested prior to shipment. MATERIALS OF CONSTRUCTION The main valve body and bonnet shall be ductile iron per ASTM A536, Grade 65-45-12. All ferrous surfaces shall be coated with 4 mils of epoxy. The main valve seat ring shall be CF8M stainless steel. Elastomers (diaphragms, resilient seats and O-rings) shall be Buna-N. The control and solenoid pilots shall be stainless steel, as shall the needle valve and control line tubing. The solenoid and limit switch enclosures shall be explosion-proof and suitable for operation on <voltage>. OPERATING CONDITIONS The two-stage preset valve shall be suitable for controlling the downstream pressure at <X> psi at flow rates up to <X > gpm. ACCEPTABLE PRODUCTS The two-stage preset valve shall be a <size> Model 127-9, <globe pattern, angle pattern>, with <150# flanged, 300# flanged> end connections, as manufactured by OCV Control Valves, Tulsa, Oklahoma, USA.

Other positions are acceptable but may not allow the valve to function to its fullest and safest potential. In particular, please consult the factory before installing 8" and larger valves, or any valves with a limit switch, in positions other than described. Space should be taken into consideration when mounting valves and their pilot systems. A routine inspection & maintenance program should be established and conducted yearly by a qualified technician.
