Pressure Regulation

Pressure Regulation

City Gate/Pipeline

Fisher EZH & EZHSO

Types EZH (Spring-to-Close) and EZHSO (Spring-to-Open) regulators are accurate pilot-operated, pressure balanced, soft-seated regulators. They are designed for use in high pressure natural gas transmission/city gate stations, large capacity distribution systems, and power plant feeds. They provide smooth, reliable operation, tight shutoff and long life.

FL Series Pressure Reducing Regulators

The FL Series regulators are accurate pilot-operated, pressure balanced, soft-seated regulators designed for high pressure transmission/city gate, large capacity distribution systems and power plant feeds. The FL Series provides smooth, quiet operation, tight shutoff and long life. It utilizes a main valve actuator, a Type PRX pressure reducing pilot, and a Type SA/2 pilot supply pressure regulator.


Fisher Vee-Ball Series

The Fisher V150, V200 and V300 Series ball valves feature segmented V-Knotch balls which provides wide rangeability and low full-open pressure drop. The soft seat provides tight shut-off for positive lock-up.

District Station

EZR Relief Valve / Backpressure Regulator

The EZR pilot-operated, pressure relief valve or backpressure regulator is typically used in city gate and district stations as a relief valve for overpressure protection, or in commercial and industrial applications as a backpressure regulator. It provides smooth, quiet operation, tight shutoff, and long life. The Type EZR can be converted to a pressure reducing regulator simply by changing to a pressure reducing piloting system.

1098-EGR &1098H-EGR Pressure Reducing Regulators

Types 1098-EGR and 1098H-EGR regulators provide economical and accurate pressure control in a wide variety of applications; natural gas distribution systems; fuel gas supply to industrial boilers, furnaces, ovens, and mixers; and large commercial / industrial establishments such as shopping centers and schools. They are also used in plant air service and in liquid service where a slow stroking time (approximately 30 to 90 seconds) is desired on both opening and closing the main valve.

Type 99 Pressure Reducing Regulator

The Type 99 gas regulators provide a broad capacity for controlled pressure ranges and capacities in a wide variety of distribution, industrial, and commercial applications. It has a Type 61L (low pressure), Type 61H (high pressure), or a Type 61HP (extra high pressure) pilot integrally mounted to the actuator casing. Type 99 can handle up to 1000 psig inlet pressure. This regulator comes standard with O-ring seals on the guide bushing and valve carrier to keep main valve body outlet pressure from interfering with outlet pressure in the lower casing assembly.


CS Series Direct Operated Regulators

The CS200 and CS400 Series Direct-Operated, spring-loaded regulators have been engineered to fit a multitude of commercial and light industrial installations pressure-reducing applications. Flexibility is provided by the numerous body sizes, outlet pressure settings/orifice sizes, and, the combination of the 360-degree rotatable union ring along with a rotatable upper casing provide simplified vent position, especially in tight spaces or awkward installations. Additionally, the CS400 Series offers multiple overpressure protection, integral monitor protection and slam-shut module options. End connections 3/4 – 2 NPT.
