Flexibility of in-line repair ASME 2500 Class isolation valves for vents and drains in high pressure, high temperature power applications

ASME 2500 Class: Flexibility of In-line Repair

MOGAS SC-3PC valve

The SC-3PC has a three-piece body assembly with two proprietary body seals that allow the valve body to be easily removed while the end connections remain in line. The design also allows the valve body to be tested after repair, prior to insertion back in-line.

The SC-3PC is used in power plants for isolation of high pressure / high temperature applications.

In-line Repairability

Three-piece valve assembly
Valve body can be easily removed while end connections remain in-line
Allows valve body to be tested after repair, prior to insertion back in-line

Ball & Seats

Mate-lapped for 100% sealing contact
Ensures absolute shutoff
Corrosion resistant
Seats are protected from flow in open / closed position
Seats are field replaceable

Seat Spring

Assisted by line pressure, provides a constant mechanical force on ball against seat to maintain seal

Body Gaskets

Two proprietary body joint seals of Inconel 718
Gold plating of gaskets creates a metallic permatext to assist in sealing
