How to fix a leaky flow block?

Defects in the contact surfaces of the valve and body can be eliminated by lapping the sealing surfaces. The contact surfaces are usually made of bronze. To do this, it is necessary to dismantle the cover, remove the shutter, and, if necessary, the housing. Grinding is performed with diamond pastes of various grain sizes with a gradual transition from coarse to fine.

 It should be borne in mind that in wedge gate valves after several lappings, the valve sags, which leads to leakage even with polished wedge surfaces.

 If pipeline fittings are out of order at your enterprise, PZTA JSC is ready to provide repair services.
