Forged Ball Valve

Description of Forged Ball Valve:
ZECO forged ball valve is divided into forged two-piece ball valves and forged
three-piece ball valves, as well as small diameter forged ball valves and large
diameter forged ball valves, which are widely used in various high-pressure
industrial conditions. Usually pressure at 600 lb, 800 lb, 900 lb, 1500 lb,
working temperature in various pipeline - 46 ℃ ~ 425 ℃.Of course, 150LB and
300LB of low pressure are also frequently used in the list of users. Its
materials also include ASTM A105, ASTM A182 F304, ASTM A182 F316, ASTM B283
C61900, ASTM B148 C95800 and other forging materials.
Features of Forged Ball Valve:
1. ZECO forged ball valve has double piston effect seats which are pressure
energized in both directions. So the seat rings are always pushed against the
ball by the pressure from upstream/downstream or from the cavity. If the
upstream seat fails, the downstream seat can still ensure a tight seal. Widely
used in specific applications or for some pipe pressure testing. Since double
piston effect valves do not have the self-relieving function, the automatic
cavity-pressure relief valve shall be provided, unless otherwise agreed;
2. ZECO forged ball valve has one self-relieving seat. If the force created by
the body cavity pressure is greater than the preloaded spring force plus the
force created by the pressure from pipeline, the cavity pressure releases via
the self-relieving seat, the double piston effect seat still functions a tight
seal;
3. ZECO forged ball valve is available in additional configurations upon
request, like Delta ring seat design, it’s easier to seal;
4. ZECO forged ball valve is available in additional configurations upon
request, like Lipseal design, it’s easier to preserve.
