Metal Bellows Shut-Off Valve
The Metal Bellows Shut-Off Valve we sell at ORFA Industrial Products Industry and Trade Inc. offers high reliability and performance in industrial applications. This valve is designed for use in demanding environments, such as power generation, refineries, petrochemical plants, the chemical industry, food processing plants, and paper mills.
Product Features
The Metal Bellows Shut-Off Valve provides a long-lasting, maintenance-free solution by providing stem sealing with a double-walled stainless steel bellows and a pure graphite safety packing. The valve maintains a seal even if the bellows is damaged by tightening the hexagonal bushing on the stem. Operating on a standard metallic sealing principle, this valve features a conical seat and clapper structure. This new design provides increased throttling performance compared to a straight clapper.

Working Principle
Working Principle
The Metal Bellows Shut-Off Valve offers high performance and reliability. It minimizes maintenance requirements by effectively sealing the shaft.
Double Walled Stainless Steel Bellows: The stainless steel bellows prevents the fluid inside the valve from leaking out and its double-walled structure increases the sealing performance.
Safety Pure Graphite Packing : Activates in case of bellows damage and maintains the sealing performance of the valve.
Conical Seat and Disc Structure : Provides increased throttling as fluid flows through the valve. The conical seat and disc design provides more effective flow control.
Metallic Sealing Principle : Seals with metal-to-metal contact and provides reliable sealing even under high temperature and pressure.
Frictionless Operation: Metal bellows shaft seal operates almost frictionlessly during rotation of the handwheel, thus providing maintenance-free and long-lasting operation.
Optional Valve Variations: It can be offered with 26 different valve variations suitable for different applications.
Extra Features
Flat Lubrication Nipple: Facilitates valve maintenance.
Locking Device: Prevents unwanted opening or closing of the valve.
Ductile Iron Cover on Cast Iron Valves: Increases durability.
Position Indicator: Indicates whether the valve is open or closed.
Optimized Cover for Accessories: Allows for easy installation of additional parts.
Non-Rising Handwheel: Ensures that the valve remains compact during opening and closing operations.
Areas of Use
Energy Production: Provides reliable operation under high temperature and pressure.
Refineries: Long-lasting thanks to its chemical resistance.
Petrochemical Plants: Can be used safely in abrasive and corrosive environments.
Chemical Industry: Provides reliable sealing and durability.
Food Facilities: Provides a hygienic and safe solution.
Paper Mills: Durable under harsh production conditions.
