Flow control valve to reduce cavitation and noise at high differential pressure

Features

Orifice butterfly valve controls flow at high differential pressure
1. Anti-cavitation structure
Achieves flow control at high differential pressure by multiple distributed
nozzles which divide the flow at all opening degrees.
2. Low noise
Possible to modulate the flows at high flow rate without making noise.
3. Light and compact
More compact than sluice and globe valves by adopting the butterfly valve
structure.
4. Water sealing by rubber seat
Has excellent water sealing, same as the JWWA B 138 butterfly valve.

Merit

1. Standard Butterfly valve

As the valve opens, a crescent shape opening gets bigger.
2. Multi-hole variable orifice valve
The breakdown of flow in to multiple small jets reduces noise and makes throttling more effective with less cavitation, even as the valve opens up.
3. Orifice butterfly valve
Cavitation is suppressed by multiple distributed nozzles which divide flow and the valve opens . This can achieve higher performance than multi-hole
variable orifice valves.
