Needle Valves :

Needle Valve is call like that because of the chronic rod which replace the shutter above a little orifice diameter in relation with the nominal diameter of the valve.The displacement of the rod, if it is a fine thread is slow and the fact that until a good number of turns don’t spin the liquid pass section is minimum, converts that valve in a good caudal regulator, with not much erosion and cavitations to big differential pressures.They are usually used for instruments, calibers, etc., because very precise strangulations are achieved, also using them in applications with big pressures and/or big temperatures.CONSTRUCTION MATERIALSThe body can be in brass carbon steel, stainless steel, bronze and interiors are constructed of SS316 Stainless steel and its gasket in Teflon.TYPESType 3000 – 6000 – 10000 PSI (CWP)CONNECTIONWire BSP, NPTDIAMETERSFrom 1/8” to 1”
