Description Material Performance Product Size Specifications

Valve sleeve type sewage valve is evolved from the gate, the use of gear rotation to drive the 90 degrees to achieve the purpose of opening and closing the valve stem. Moment is small, the operation is simple, easy to achieve fast opening and closing.
The valve sleeve type drain valve has the advantages of simple structure, good sealing performance, small volume, light weight, and less consumption of materials, installation of small size, especially the drive, regular sewage drain valve PN 20MPa high pressure boiler, can five channels at the same time can also be a channel of sewage, sewage.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
