A needle valve is a type of valve that adjusts flow gradually and precisely via a rotating needle mechanism. The VLV series needle valve is used for fine flow adjustment in high-pressure liquid and gas lines.
It is designed to operate in the 10,000 PSI (700 bar) class and provides reliable operation up to this pressure.
The body is made of 4140 steel and the needle is made of stainless steel (SS316); this combination provides high strength under high pressure.
It has a 3/8″ NPT (National Pipe Thread) connection standard.
It operates safely between −20°C and +200°C.
Full sealing is achieved using PTFE (polytetrafluoroethylene) seals.
The rotating needle mechanism allows flow to be adjusted finely and precisely; opening/closing is performed with the rotating-type needle.
It is used in petrochemicals (high-pressure liquid/gas flow control), hydraulic systems (fine adjustment of hydraulic oil flows), laboratory and test setups, the energy sector (gas and oil flow control), and process control applications requiring precise flow.
VLV series needle valves are used in high-pressure lines requiring precise adjustment, to provide safe flow control in hydraulic torque and tensioning systems.
It is manufactured in compliance with ISO 9001, ASTM and DIN standards.
