Gear Operated Ball Valve

Description of Gear Operated Ball Valve:
Large size ball valve if adopt manual operation will reduce the efficiency of personnel, even if many people help may also be because of the large size of excessive torque can't open or close the valve, so the large-diameter ball valve ZECO basically adopts the gear operation, the gear can drive way through the gear structure greatly reduce open or close the valve torque, could have been three operations may be only one operation can be completed. In addition, ZECO can manufacture turbo heads with waterproof grade or full spray coating according to customers' requirements.
Features of Gear Operated Ball Valve:
1.ZECO gear operated ball valve has a stem anti - fly out design. It is different of lever operated ball valve.In ball valve need to change the packing or for corresponding maintenance, need to clear the packing gland, in order to prevent the discharged gland, the stem will be hurt by pressure within the lumen and top fly to maintenance personnel, ZECO in a setting on the stem for stem convex in gland place, no matter how much lumen pressure stem fly out burst damage will not happen;
2.The connecting parts of the valve body and the left body of ZECO ball valve are cushion seals. In order to prevent the sealing leakage caused by fire, high temperature or vibration, ZECO designed the connection between the valve body and the left body as metal and metal contact, forming a flange to ensure no external leakage;
3.ZECO gear operated ball valve is designed with anti-static device. When the ball valve in the process of opening or closing, non-metallic materials on the surface of the ball and seal friction generating electrostatic, such as static medium is derived and the line is combustible materials will be very serious incidents, so ZECO design on the stem and ball anti-static device, composed of spring and the metal ball, which can be produced by electrostatic export the valve body;
4.ZECO gear operated ball valve is designed to be fire protection. In case of fire, non-metallic materials such as packing and seat or some materials with low ignition point will be seriously burnt down and lead to serious leakage and expansion of fire situation. The fire-proof structure of ZECO Valve company can ensure that after these non-metallic materials are burned down, the leakage can be prevented through the metal seal of the ball and valve body to ensure the normal operation of the pipeline.

Forged Ball Valve

Description of Forged Ball Valve:
ZECO forged steel 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.
As a industrial valve manufacturer, ZECO always adhere to exceed customer expectations, to provide customers with more value-added services and products as the ultimate goal.
