Pressure seal gate valve manufacturers in India

Speciality Valve is one of the leading Pressure seal gate valve manufacturers in India that delivers high-performance valves for aggressive pressure and temperature processes. They have a self-sealing system that enhances safety and reliability in mission-critical applications.

Why Required?

Under high-pressure conditions, the traditional bolted-bonnet valves tend to leak. Pressure seal gate valves are particularly suitable for such applications because their seal mechanism becomes more robust with a rise in internal pressure. They are a crucial component of power plants and other high-pressure plants.

Key Components of Pressure Seal Gate Valve:

Valve Body: Constructed from robust forged or cast steel for rigidity

Gate/Wedge: Allows for tight shutoff when closed

Stem: Facilitates gate motion, typically rising or non-rising

Bonnet: Pressure seal bonnet that forces the seal ring on pressure

Seal Ring: Provides leak-free sealing with pressure increase

Working:

Pressure seal gate valve works by raising a wedge-shaped gate up or down between two seating surfaces through a threaded stem or actuator. Pressure seal design utilizes internal system pressure to push the bonnet seal into tighter contact, offering better sealing performance at higher pressure.

Advantages of Pressure Seal Gate Valve:

Leak-free construction for high-temperature and high-pressure applications

Lightweight and compact in relation to bolted-bonnet designs

Self-seal when pressurized for added safety

Low maintenance with extended lifespan

Best suited for thermal shocks and cycling
