Industrial Valves #244987

Flexible wedge gate valves are designed for high pressure and high temperature applications where tight shutoff and reliable operation are critical. the wedge is of one piece and fully guided with cast central hub. It compensates for the distortion of the body seat by thermal cycling and bolt stresses from pipe connections and provides a tight seal in low differential pressure condition. It also prevents sticking or galling in severe operating conditions.

All VOLK globe valves use a body guided disc which is held concentric at all times with the body seat. Guiding is done over the full length of the disc to provide a valve with a fully guided disc.Bonnet: With cooling chamber, it increases the packing life and sealability by maintaining packing at normal temperature. The eyebolt type gland bolt makes repacking easy.

Seat: Renewable and easy to replace seat ring are seal welded to minimize distortion from body stress. Hardfaced seat ensures long service life, better resistance to heat, corrosion and erosion.Retainer bolt: Studs establish the initial seal of the pressure seat joint.
