Introducing the Greno Industrial Supply Valve or G.I.S. Relief Valve

Consistent Under Pressure for 40 Years

The G.I.S. 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 to 1100 degrees Fahrenheit. Design advantages include:

• High accuracy and repeatability. Remote operation means 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 also eliminates unnecessary opening of power control valves.
• Increased safety and ease of adjustment. Adjusters are located on the remote unit, so 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 Safety valve is eliminated by pressure-loading design.
• Reduced maintenance. Modular design facilitates ease of maintenance and/or replacement.

The G.I.S. Relief Valve has been used on several US naval ships for four decades, as well as large infrastructure systems, such as power generation plants. The economic advantages of the G.I.S. Relief Valve are directly related to its superior design and construction. Numerous existing power control systems are reduced to a single process, reducing annual maintenance costs.

We have engineered a remote pilot triggering system, allowing our valve to use a hydraulic pressure system which uses up to four times the force of our competitors spring-loaded valve. Once the stellited hardened nozzle is seated, it creates a leak-free seal to the upper pressure disc. At that point all pressure is vented and there is no potential for chattering when the valve is seated. This reduces the possibility of damage to the valve during the application process.

Greno’s engineers can customize the G.I.S. Relief Valve assembly to work for your facilities system and specifications. This is the safest, longest lasting industrial supply valve in the industry. The G.I.S. Relief Valve is manufactured in our 60,000 square foot facility that features state-of-the-art machining capabilities. You can relax knowing we offer 24-hour emergency service.
