ST00MG08_Needle Valve_High Pressure Valve_Neptune Valve丨Neptune Industrial Group Inc

Parameter

○ Port type: UBJ ball joint welding (OD sleeve, BW butt welding, SW socket welding, UBM sleeve welding, thread, etc.)

○ Working temperature: -20 ℃~520 ℃

○ Pressure environment: 6000PSI up to 10000psi (689bar) maximum

○ Drive mode: One character handle, handwheel

○ Nominal diameter: 3mm~28mm (1/8~1 ")

○ Valve body material: 304, 316, 316L, 321, Hastelloy, Monel alloy

Performance

○ Dual stem design: The upper stem is threaded hardened, the lower stem is smooth surface hardened, and the lubricating grease on the threads of the upper stem is isolated from the system medium

○ The linear operation of the non rotating lower valve stem replaces the spiral operation, thereby avoiding damage to the valve seat and valve tip components

○ Reduce the friction between the packing and the lower valve stem

○ Valve accessories can be selected according to different pressures, temperatures, and media to ensure that the valve will not leak under specific working conditions

○ At the corresponding temperature, the seal will not experience loose sealing

○ It can also be achieved by replacing the valve core to cut off and adjust the flow

○ The entire valve stem can also be customized according to user needs

○ Optional sealing materials: PTFE, PPL, graphite

○ Optional valve panel fixation

○ The handle has multiple colors or handwheels to choose from

○ Each valve undergoes a sealing test before leaving the factory, and is subjected to a sealing test at 5% of the rated working pressure and 1.5 times the water pressure

Application

The double ends of the needle valve with flexible joints are equipped with flexible joints for easy on-site disassembly and maintenance of instruments; The valve body is made of integral forged stainless steel or alloy steel, with a pressure resistance of PN100-PN420; Built in precision conical needle valve core, achieving precise adjustment and reliable shut-off of micro flow, widely used in pressure gauges, transmitter pressure pipelines, and high-pressure, high-temperature, or high-purity medium systems that require frequent maintenance, while ensuring sealing and improving installation flexibility.
