Gear operated gate valves can be used as efficient on/off valves for two-way flow.One of the most notable features of this type of gear operated gate valve is its straight through, unobstructed path in full open condition and high opening and closing efficiency.Therefore, industrial gate valves are characterized by minimal turbulence and pressure drop in operation. Although geared gate valves are intended for service with on/off service, they are not recommended for throttling purposes because the flow resistance curve does not provide the advantage of a regulator or other regulating valve. The gear-operated gate valve has a flexible wedge, which can also be customized for other types of seals, that moves along the body during opening and closing and remains in place through a guide slot to minimize friction between the body seat and the wedge.This design is particularly suited to compensate for the slight thermal distortion of the valve's own piping to ensure a better seal between the body and the wedge seat.
As the New Year is approaching, the production workshop of ZhengFeng valve group is still preparing a batch of 18-inch and 1,500LB cast steel gear operated gate valves for export to the United States. ZhengFeng has high standards and high requirements for its products. Because of this spirit of craftsmanship, ZhengFeng has won many customers' recognition.
