 Guides in the wedge and on the valve body ensure a uniform closure, safe operation ensured as the guides prevent overloading of the stem.

Stainless steel stem with rolled threads for high strength.

 The valve can replace stem seals under pressure.

Full bore.

 Body inside and outside fusion bonded epoxy coating with excellent corrosion resistant performance.
