GS

The Valtek GS is a fully integrated valve-actuator-instrumentation package for a continuous process, non-critical flow loop controlled throughout the plant. Engineered from the ground up, the Valtek GS has achieved optimum performance at minimum total cost. It does this by pursuing the simple design philosophy of building an instrumented control valve package that is “everything it needs to be” by providing the breadth and depth of engineered control under the Valtek trusted name.

Double Top Stem Guiding moves the critical function of assuring alignment of the trim out of the flow path

Single Piece Plug & Stem assures integrity of the assembly, avoiding side load fracturing

Oversized Stem provides greater durability for high-pressure applications

Plug Contours provide flow characteristics with higher rangeability than cage designs

Screwed Seat coupled with plug to seat modulation, eliminate the need for cage, increasing flow capacity

Compact Design integrates actuation and positioner to provide lightweight, small footprint, & cost-effective design

Bolted Bonnet eliminates service issues related to thread designs

1-Stage MultiStream Severe Service Trim option is available for noise and cavitation reduction
