Introduction
High-performance resilient wedge gate valves offer premier isolation reliability and perfect sealing performance across fluid distribution systems. The optimization of the compression sealing design eliminates lateral friction, fully protecting internal surfaces from premature wear over years of continuous service. Featuring a flawless, high-adhesion protective epoxy coating, these heavy-duty pipeline valves guarantee maximum resistance against corrosion in demanding environmental conditions.
Key Features
Frictionless primary compression sealing, bottom-draining wedge fully coated with vulcanized EPDM or NBR rubber, high-security dual upper O-ring secondary seals, body-to-bonnet fasteners sealed against external oxidation, high-durability epoxy resin coating with a minimum thickness of 200 microns, comprehensive prearrangement available for optional electric motorization
