Features:
1. Design of Discharge hole is reasonable, the discharge hole of above DN300( including) can allow one-hand entry, the role of sewage discharge is stronger, save cleaning filter time by pipeline maintenance workers.
2. Because vortex flow is easy to be formed when medium passing through the filter net, the impurity is not easy to precipitate at the bottom of the bonnet, but it is easy to attach to the net wall of the filter net. Combined with previous design experience, the inside of the bonnet is designed as concave type, and it is easier for impurities to precipitate at the bottom of the bonnet to effectively extend the cleaning time.
3. A support column is added to the inner wall of the valve body to prevent deformation of the filter net and increase the service life of the valve.
