Product Description
Internal Thread Needle Valve
Level Gauge Plug Needle Stop Valve
Level gage valves are used to isolate a level gage from its host process for maintenance, inspection, andother ancillary operations. Water Gauge valve cocks are used for water level gauge (reflex alass levelgauge, transparent glass level gauge, glass tubular level gauge) . is type of needle valve, have isolating balinside, once the glass broken, the ball will block the water flow out.
The needle valve is a precision flow control valve widely used in industrial applications where accurate control of flow and pressure is critical. The valve body is made of durable materials such as stainless steel to ensure long-term reliability and corrosion resistance. Its small stem travel and minimal contact area between the valve seat and stem provide precise flow control and excellent sealing performance.
