Double Beat Valve
Double Beat Valve – Series - 1910
Dual Disc Pressure-Balanced Isolation for High-Pressure Applications
A Double Beat Valve is a globe-type valve featuring two parallel discs and matching seats that operate simultaneously to balance fluid pressure.
This design significantly reduces operating torque, making it ideal for high-pressure and large-diameter pipelines requiring tight shut-off and efficient isolation.
Its balanced configuration minimizes hydraulic load on the stem, resulting in smoother operation and longer service life.

Working Principle:
Open Position
The stem lifts both discs simultaneously off the seats. The balanced pressure on each disc reduces operating effort. Full-bore opening ensures high flow capacity.
Closed Position
Both discs are seated simultaneously for double sealing. Provides tight shut-off under high-pressure conditions.
Balanced Operation
Dual-disc design offsets line pressure on the stem. Enables smooth operation with lower actuator torque compared to single-seat valves.
Key Features & Advantages
- Lower operating force due to balanced disc design
- Reliable double-seal performance under high pressures
- Ideal for large-diameter and high-pressure lines
- Long service life with rugged construction
- Reduced risk of leakage or stem loading
