Hand Wheel Gate Valve

Product Details

Handwheel Operated Gate Valve by choosing different materials, steel gate valve can be used in water, oil, steam, nitric acid, acetic acid, strong oxidizing medium and urea and other media. It has manual, bevel gear drive and electric drive.

All handwheel operated gate valves have backseat threaded in the bonnet, or for the pressure seal valves, welded to the bonnet. Into pressure seal the hard facing is satellite 6 or equivalent.

The stem of handwheel operated gate valves are forged from one piece and ACME threaded, then mechanized and finally provided with a smooth finishing in order to minimize friction.

In handwheel operated gate valves, the union of stem and wedge shall be in T form, designed to prevent the stem disengaging itself from the wedge while being in service. This design includes a conical raised surface that presses the seat against the bonnet backseat in the fully open position.

Design Features

Design standard: API 600.

Small flow resistance for fluid

Only a small force is required for opening/closing.

No limitation on the flowing direction of the medium

During opening and closing process, the friction between the disc wedge and the seat is small, so the sealing is reliable ensuring tightness and long service life.

The valve is designed in a back-seat structure.

The valve stem sealing is realized by the collaboration of flexible and woven graphite. ensuring a more reliable tightness.

Optional pressure seal bonnet type.

Optional solid-wedge type

Optional non-rising stem structures

Optional jacket structure
