Needle Valves

Product ID: SNV Series - Delrin soft seat, 6000 psi

The needle valves are applied to regulate flow and provide repetitive bubble-tight operation. SNV series soft seat valves provide high capacity of bi-directional flow and are easy cleaning even in dirty service. They are standard with a replaceable Delrin seat that gives premium tightness at closure. We offer a variety of connections in NPT, BSPT and BSPP. They are offered with 316 stainless steel and carbon steel to meet the requirements of NACE for soft seat needle valves. SNV series in angle type is available on request.

The hard seat valves with non-rotating tips to protect metal seat from galling are available. Generally, a hard valve requires a hard seat and vice versa. High pressure suitable for 10,000 psi and graphite seals for high temperature requirement are available depending on request. The quality needle valves have stem packing below the threads, and this can prevent lubricant washout, thread corrosion and the contaminant from entering the thread area.

Founded in 2000, Vertex specializes in manufacturing needle valves, valve manifolds, compression fittings and twin ferrule tube fittings for chemical, petrochemical, oil refineries, shipbuilding, power generation, and paper industries. Please do not hesitate and contact us today for details about the products.
