Features
The valve cage adopts its own patented multi-stage decompression structure to ensure the service life of the valve under large differential pressure conditions, with low noise and low vibration.
The switch is fast and the switching time is less than 1s, which meets the needs of fast switching.
Accurate adjustment allows the compressor to approach the surge limit and the negative pressure condition to operate reliably.
The disc is available in a combination of soft and hard seals for ANSI Class V and Class VI seals.
