Vacuum supply valve
Product Description
When the water column in the pressure system breaks and forms a vacuum, the vacuum supply valve quickly opens to supply air to the system, limiting the vacuum pressure within the safe design of the system and protecting equipment safety.
Product Features
The intake volume is large. Full diameter, streamlined flow channel, with a diameter of up to DN800 and a large intake volume.
Open quickly. Adopting lightweight springs, the spring force is only used to support the weight of the valve disc.
Good low-pressure sealing performance. Adopting a sealing structure that combines soft and hard sealing, it will not leak water even under low medium pressure.
The effect of preventing flow interruption and bridging water hammer is good. It can be combined with a micro exhaust valve to form an injection micro exhaust valve, preventing the occurrence of water hammer.
The structure is simple and reliable. The free valve disc structure has few internal components, reliable structure, and few faults.
Online detection is convenient. Equipped with a testing mechanism, it is easy to determine whether the valve is faulty.
