توضیحات محصول
Floating ball valves mean the most conventional type amongst all other ball valve designs; it is featured by the action of a free-floating ball that moves in response to fluid or mechanical pressure. Floating ball valves
constitute an optimal option for On / Off applications on the oil, gas and process industries. They are quarter turn valves having proved excellent tightness rate and can be operated by means of a manual hand lever,
worm gear and also actuators. Some salient features of the Series BV4- API-F are amongst others:
Full bore ball design.
Reliable seat sealing helped by the pressure of the line medium.
Fire Safe design; (optionally), auxiliary metal seals are provided to avoid internal and atmospheric leakage of the valve when subject to
overheating conditions. This feature is compliant with API 607, API 6 FA BS 6755.
.Reliable stem sealing, blow out proof stem design and V-shaped packing units around the stem.
Anti static stem.
Key locking device, pad locking and stroke limiter
Trunnion ball valves have a mechanical means of anchoring the ball at the top and the bottom, this design is usually applied on larger and higher pressure valves (say 4 inch and above 600 psi and above). They constitute an optimal option for On / Off applications on the oil and gas industries. They are quarter
turn valves having proved excellent tightness rate and are commonly operated by means of a manual worm gear or electric actuators. Some salient features
of the Series BV4-API-T are amongst others:
Emergency grease injection device, to keep the emergency tightness to the
seats and stem in the event of soft goods damage.
.Fire Safe design; (optionally), auxiliary metal seals are provided to avoid
internal and atmospheric leakage of the valve when subject to overheating
conditions. This feature is compliant with API 607, API 6 FA, BS 6755.
Double block & Bleed function.
Self relief of built up pressure in the body cavity by propelling the ball seat.
Reliable stem sealing, blow out proof stem design and V-shaped packing units
around the stem.
.Anti static stem.
