SISCO is a one-stop superstore for top-grade components such as the butterfly valve, gate valve and check valve. As a trusted supplier, we are committed to product quality and performance. SISCO--regulated flow.
The interference fit between a valve disc and a seat has been accurately calculated, and the sealing surface of disc has undergone polishing treatment, which dramatically reduces operation torque and facilitates operation.More
To shape an oblique con seal surface by the disc and seat, a seal specific pressure is applied on the stem driving torque, which successfully prevents possible leakage due to ageing, cold-flow features or loss of seat elasticity.
Its dry stem design makes sure that the stem is totally isolated from media within a pipeline.
With small operating torque and light weight, the product is easy to install and maintain.
It is able to work under PN25 working pressure. Owing to the unique design, our flow control device exceeds the standard pressure limit of traditional like products whose maximum pressure is PN16.More
With the help of the dry stem structure, the stem is absolutely separated from media. Therefore, we apply standard materials to manufacture stems so as to cut cost.
Its PTFE-clad seat is capable of protecting the body against corrosive media.
Due to a dry stem design, the stem is wholly separated from media and makes use of standard materials.
The bolts and other components of body are manufactured from stainless steel. Its design is proud of compact structure, small size, high strength and corrosion resistance.
The product can be operated by the handle, worm gear or the electric actuator.
During the opening or closing of valve, its stem will not move up and down, which saves installation space.
