Description: Needle Valves are built for regulating and positive shut - off in impulse and instrument lines and other small lines systems under pressure up to max 10000 psig. The valves are built using materials and design that would adapt to extremely erosive conditions. Especially when in combination with corrosive media the valves are drop forged in F316, F304 stainless steel with integral bonnet and needle point disc. The integral bonnet construction eliminates the disadvantages associated with a bonnet-to-body connection on high pressure inside screwed bonnet valves, maintaining accurate alignment of stem and exact mating of disc and seat surfaces. The valves are featured with seat orifice contour and stem pitches, providing optimal flow characteristics for accurate manual regulation of high-pressure flow. The valves are available in wide selection of materials AISI 316, AISI 304, special grades steels with design configuration of screwed bonnet, integral bonnet, and solid bar stock construction or drop forged for sizes 1/4″ to 2″ and end connections to BSP / NPT, flanged as per different requirements. These valves are widely used in general applications like steam, gas, water, and oil and include a wide range of acid and alkaline fluids, petrochemical and other organic substances.
