DIN-F5 Non Rising Stem Metal Seated Gate Valve DN50-DN1200

DIN-F5 Non-rising Stem Metal Seated Gate Valve

1. PRODUCT PROFILE

Metal seated wedge gate valves are primarily designed for the flow isolation of a length of pipeline or piece of equipment. It uses a ductile iron gate that houses bronze rings to ensure a watertight seal. The non-rising stem design ensures the stem thread is adequately lubricated by the water passing through the valve. In essence, the whole internals are water dependent for lubrication, a factor that safeguards the longevity of the valve.

2. FEATURES

· Bronze wedge nut with lubricating abilities providing optimum compatibility with stem.

· Face ring which firmly secured to the wedge, machined to a fine surface finish to ensure optimum contact seal with body seat ring.

· Wedge with guides, ensuring uniform closure.

· A large through bore housing for the stem in the wedge prevents stagnant water or impurities.

· Round EPDM bonnet gasket fixed in a recess.

· Countersunk and sealed stainless steel bonnet bolts encircled by the bonnet gasket.

· Full bore.

· Internal and external two-pack epoxy coating.

· For horizontal or vertical installation.
