For Power Plants MOGAS is one powerful partner!
MOGAS is well-known throughout the power industry because they have solved issues that routinely plague power plants – leaking valves, seat erosion, blown packing, and the inability to isolate critical equipment – all of which contribute to significant heat rate loss and safety concerns.
What sets MOGAS apart is more than just their utilization of sound design, manufacturing and testing practices. They’ve made it a habit to carefully listen to end-users’ performance issues and goals, and have taken their feedback into consideration when engineering each and every component of their valve line.
No leakage, limited maintenance and superior reliability, make a MOGAS valve the easiest and most cost effective valve to operate. The MOGAS selection of valve solutions lets you choose the design, trim, materials, and coatings that best fit your severe service application.
MOGAS C-Series
The C-Series valve is the best choice in large bore isolation applications. The valve has been designed to withstand high temperatures up to 1652°F , and high pressures up to 43,000 psig. By working with leading power producers, MOGAS engineers have successfully designed the C-Series valve line which isolates under the extreme conditions found in today’s power plants. With more than 25 years of engineering expertise, each C-Series valve is designed specifically for the application.

MOGAS FlexStream
Innovative Technology — A Patented Design MOGAS now offers FlexStream® — an engineered rotary control ball valve solution that incorporates a direct mounted actuator control package. Its flexible design, combined with superior performance in controlling the fluid flowstream, make FlexStream the preferred choice for extreme conditions.
- Designed to Give You More Control
By forcing the process fluid to turn through a series of right angles, the fluid can be controlled at each stage of pressure letdown. Right-angle turns and expanding flow passageways remove kinetic energy from the fluid, while lowering pressure in a controlled manner. - Media

MOGAS Gen-X
MOGAS Gen-X Metal-Seated Severe Service Ball Valves are engineered in accordance with ASME TDP-1 1998. The Gen-X valves are built and tested for the prevention of water damage to your Steam Turbines. The Cold Reheat Drain, Hot Reheat Drain, and Main Steam Drain Gen-X valves meet and/or exceed TDP bore and reliability requirements.
Dual Metal Alloy upstream and downstream seats with Chrome Carbide HRC 65 Hard Coating prevent downstream sealing damage from flashing, especially in carbon steel Cold Reheat Lines. The MOGAS Gen-X Power Product Line is offered for both automated on/off and manual on/off valve applications throughout today’s Power Plant.

MOGAS PORV
High Performance Valve Contributes to Plant Safety
ASME 1500 / 2500 / 4500 Class
Prevents Excessive Pressure
The MOGAS PORV, a pneumatic actuated pressure relieving valve, prevents excessive system pressure accumulation. The set pressure of the PORV is lower than that of the spring loaded safety valve to prevent or reduce the number of lifts of the safety valve, thus extending their life. The PORV is available either non-stamped or with the “V” stamp. The “V” stamped PORV has been flow certified by the National Board of Boiler and Pressure Vessel Inspectors.
The PORV operates as a system. The MOGAS ball valve is normally closed. The pressure switch senses steam pressure and closes an electrical switch when the pressure exceeds a predetermined point. This in turn energizes the solenoid valve, which pressurizes the “to open” cylinder port of the pneumatic actuator, opening the ball valve. When the pressure switch senses that the steam pressure has returned to normal, the electrical switch within the pressure switch opens, de-energizing the solenoid valve and closes the MOGAS ball valve.

Sizes
- 2-1/2 to 4 inch
