P99 Pressure Reducing Regulator The P99 gas regulators provide a broad range for controlled pressure ranges and capacities in a wide variety of distribution, industrial, and commercial applications. Features • Wide Variety of Applications — Natural gas distribution systems, gas supply to industrial boilers, furnaces, ovens, mixers, plant air service, oxygen and ammonia service, and large commercial establishments such as shopping centers and schools. • High Accuracy — Keeps constant inlet pressures to downstream equipment by accurately controlling distribution system pressures at widely varying flow rates and supply pressures for maximum efficiency and best operation, or by eliminating the need for pressure-compensating meters by holding a steady pressure to the meter inlet. • No Atmospheric Bleed — Loading pressure bleeds downstream through pilot via downstream control line. No bleed occurs when regulator is shut off. • Easy to Maintain— Valve disk and orifice can be inspected without removing body from pipeline. Union nut connection permits quick removal of actuator and pilot from body. • Tight Shutoff — Heavy mainspring working through a lever provides a high seat loading force for tight shutoff P99 Specifications P99 Output Ranges Ranges Pilot Versions Maximum Pilot Supply Pressures Temperature Range Weight Approximate 2" NPT 0.25 to 2 PSIG 2 to 10 PSIG 10 to 65 PSIG L LD LE H 400 PSIG with L Pilot and H Pilot 160 PSIG with LD Pilot 400 PSIG with LE Pilot –20˚ to 180˚F P99 Materials of Construction Body Spring Case Upper and Lower Casing Main Spring Diaphragm Diaphragm Plate Body Spring Case Casings Diaphragms Orifices Springs Bleed Valve Tubing Fittings P99 Main Regulator Cast Iron Cast Iron Cast Iron Steel Nitrile Steel P99 Pilot Regulator Cast Iron Cast Iron Cast Iron Nitrile Stainless Steel Steel Stainless Steel Copper Brass P99 Regulator Rebuild Kits Kit Includes P99 Nitrile Low Pressure Pilot 7/8" Orifice P99 Nitrile Low Pressure Pilot 1-1/8" Orifice Kit Includes: Diaphragm, Pusher post gasket, Body gasket, Nitrile disk assembly, Orifice, Spring case gasket.
