Stainless Steel Gate Valves

The most traditional, widely used, on-off valve approach to manufacture this type of valve is to maintain high integrity of components, traceability, process controls and tests in order to supply a superior product to for particular customers demands.

Specific attention is given to products in other than day-to-day used material, i.e. stainless steel. Basic standard of reference is API 600, but also EN 12516 can be referred to. Materials are either to ASTM/ASME standards or to EN standards, either harmonized or calculated to design conditions.

Pressure classes are normally ranging from 150# to 300# and 600#. Flanged or butt weld ends configurations are both available.

The gate valve is the widely used for large diameter, full port applications. When the valve is fully open, it allows straight-through passage through and opening that is essentially the same size as the inside diameter of the connecting pipe. This is why there is little pressure drop through an Asahi/America gate valve. The valve operates when the hand wheel and stem screw (or electric actuator) move a cylindrical plug, the gate, up and down at right angles to the fluid flow. Traditionally, gate valves have been used only for ON/OFF service, but because the unique Asahi/America sliding plug design provides a larger seating area than conventional gate valves, it can be used for throttling. This significantly larger seating area, which runs 360 degrees around the cylindrical plug, has also virtually eliminated the valve chatter normally associated with gate valves.
