Design

The GIS hydraulic pilot operated power control valve is designed for safety, durability and ease of maintenance. Its unique design provides operations reliability for systems ranging in pressure up to 3000 psi, at temperatures up 1100 degrees Fahrenheit. Design advantages include:

High accuracy and repeatability.

Because of remote operation, the pilot valve is not affected by extremes of temperature. Plus our design results in more accurately balanced boiler operations at peak loads.

Increased efficiency.

The precision of this valve allows operation closer to set point than conventional valves, and eliminates unnecessary opening of power control valves.

Increased safety and ease of adjustment.

Because adjusters are located on the remote unit, operators are not exposed to hazardous conditions when adjustments must be made. In the event of power outages, the supply valve safely operates without an external power supply.

Simmering eliminated.

Due to full valve lift, giving maximum flow at set pressure, there are no secondary lifts or closings. Leak-free operation. Steam leakage from the pilot valve is eliminated by pressure loading design.

Reduced maintenance.

Modular design facilitates ease of maintenance and/or replacement. Economy The economic advantages of the GIS valve system are directly related to its superior design. With their design, numerous existing power control systems can be reduced to a single system, trimming maintenance and supply costs. The GIS modular design also greatly reduces maintenance costs, while the elimination of steam leaks results in more efficient, economical operation. And because of the built-in flexibility of the GIS system and the expertise of out engineering staff, we can custom-design a valve that works with your existing system - so you have the option of upgrading without a complete redesign.

GIS valves are built to last.

Quality control of raw materials is meticulous; remote operation results in reduced wear on the system; hard surfacing alloys on disc and nozzle ensure durability. In addition, the pilot valve unit does not require exhaust piping or expansion joints, which eliminates piping strain and maximizes valve life.

Service

At GIS, they're service-driven. That's why they have the complete capabilities to produce valves - from design and assembly through testing and shipping - in a 60,000 square foot facility dedicated to that function. It's why we have top quality engineers, state-of-the-art CAD/CAM capabilities, and an impressive reputation for delivery in less than anticipated time. Because they put the pressure on themselves, their customers can take things a little easier. And that's the way they like it. So whether you're considering a new depressurizing system or modernizing an existing one, give GIS a call. No pressure-just performance.
