  • Flow Direction: Inlet to outlet, as specified by the valve configuration
  • Control Function: Maintains upstream pressure at the required set pressure and relieves excess pressure when the upstream pressure exceeds the set point
  • Service Media: Suitable for gas or liquid applications, subject to the selected trim and pilot configuration
  • Application: Process pressure control, overpressure protection, bypass systems, gas pressure systems and liquid pressure applications
MAIN VALVE
  • Valve Body: Fisher Type 63EG
  • Body Material: Available in various materials depending on pressure class and service requirements
  • Trim: Quick-change trim design
  • Seat Construction: Metal plug with available soft-seat configuration depending on service
  • Trim Material: Selected according to process media, pressure, temperature and application
  • Travel Indicator: Available depending on configuration
  • Bonnet: Configuration dependent
  • Internal Components: Replaceable trim for simplified maintenance
PILOT SYSTEM

The Type 63EG uses a separate pilot regulator to control the main valve.

Typical Pilot: Fisher 6358 Series Pilot

Available pilot configurations may include:

  • 6358
  • 6358B
  • 6358EB
  • 6358EBH

The pilot selection determines the applicable set-pressure range, sensitivity, capacity and operating characteristics of the complete relief valve/backpressure regulator assembly.

CONNECTION / END CONNECTION

Depending on the selected configuration, the Type 63EG can be supplied with:

  • NPT Threaded Connection
  • Socket-Weld (SWE)
  • Butt-Weld (BWE)
  • Flanged Connection
PRESSURE CLASS

Available pressure ratings depend on the valve size and body configuration and may include:

  • ASME Class 150
  • ASME Class 300
  • ASME Class 600
  • PN16
  • PN25
  • PN40

The actual pressure rating must be confirmed from the selected Fisher 63EG configuration.

SIZE

The valve is available in various nominal sizes depending on the required capacity and configuration.

Nominal Size: To be specified according to application and required flow capacity.

SET PRESSURE

Set Pressure: To be specified according to application.

The set pressure is the upstream pressure at which the pilot-operated valve begins to open/control pressure.

The applicable set-pressure range depends on the selected 6358-series pilot and spring configuration.

PRESSURE CONTROL

The Fisher 63EG can be used as:

1. RELIEF VALVE
Opens when upstream pressure reaches the predetermined set pressure to relieve excess pressure and protect the upstream system.
2. BACKPRESSURE REGULATOR
Modulates the main valve opening to maintain the desired upstream pressure/backpressure.
3. BYPASS REGULATOR
Can be applied in bypass systems where controlled pressure relief or pressure maintenance is required.
