PROBLEM: High temperature GAS service

Most consider GAS service easy, however some plants require high temperature, and this GAS was very dry.

NO Lubricity and high friction became a problem

A China customer had problems with metal seated valves for gas service, others has tried but failed, either the valves galled after short time, or speed was too slow. Customer required under 0.5 sec operation.

RENCOR developed the method to operate the valves in 30 mill /sec.

VELAN provided the valve to operate at 272 psig @ 7008 F, dry gas.

Valves OPEN Quick, operate every 5 minutes
