Parker Autoclave s valves are a non rotating rising stem design working pressures to 20 000 psi 1379 bar . Tubing sizes range from 1/4 to 1 1/2 .Tubing connections utilizes Parker Autoclave Engineers coned and threaded design.
Needle Material Code Description 1 Carbon Steel 2 Stainless Steel NVHH Needle Valves Carbon/Stainless Steel Bidirectional flow ¼ to 2 for working pressures up to 10 000 PSI Flow regulating steel or stainless steel body needle valves provide metered flow in both directions. Choice of carbon steel or stainless steel for body and trim.
Small things make big differences Although needle valves are comparably simple in construction the effects of an ill suited valve selection can be quite drastic. Problems ranging from issues with standard compliance to contamination or even process failure are typical consequences of low quality or simply inapt valves. The benefits of needle valves on the
How Needle Valve Works. Introduction. Needle valves is a kind of valve designs which have atiny opening and also have a plunger which looks great and resemble the common type of sewing needle. The objective of this kind of valve is to pave a way by which gases or liquid which flow through the valve mechanism can be controlled.
Universal Needle Valve. MstnLand s series of Universal needle valve can withstand greater pressure good sealing performance so generally used
High Performance Needle Valve Description The High Performance Needle Valve is evolved from the stop valve also called the needle valve stop valve. The difference in these two valves is that the spool of the needle valve is a sharp cone which is inserted into the valve seat like a
Features of the NOSHOK NEEDLE VALVES Compact size. All stem threads are rolled for strength and ease of operation. 100 helium leak tested to 1 x 10 4 ml/s for guaranteed performance.

Needle Valves Flow controls and Needle valves are used to reduce the rate of flow in a leg of a system consequently the restriction slows cylinder speed. Performance Data Port Options Flow Control Needle Valve Temperature Range Operating Pressure 20o to 160o F 0 to 125 psi
Valves feature a range of characteristics standards and groupings the help to give you an idea of their intended applications and expected performance. Valve designs are one of the most basic ways to sort the huge range of valves available and finding a good fit for a project or process. Common types of valves include
Marsh Needle Valves are used in oil and gas production chemical processing hydraulic equipment and anywhere a flow of liquids must be carefully regulated. All of Marsh s needle valves are bar stock machined for rugged and reliable performance. Connection sizes range from 1/8 to 1 NPT in either globe or angle patterns. When a bubble tight
Anchor Fluid Power check valves are a hard seat design and should only be used for hydraulic applications. The function of a needle valve is to control the flow of hydraulic fluid. Closing the knob of the needle valve reduces the internal orifice size thus reducing the flow rate of oil in the line. Opening the knob of the needle valve
Needle . The needle valve is similar to globe valves. Instead of a globe like disk the needle valve has a needle like disk. This is more suitable for applications that need precise regulation. Additionally needle valves are better valve control regulators for smaller quantities. The fluid goes in a straight line but turns 90 0 if the valve is

Description The needle valve can be used to control mini cylinders nozzles timing circuits filling heads bleed vents and in many other applications. The valve is also available with options such as a panel mount thread and a knob for easy adjustment. Maximum inlet pressure is Actuation Manual / Hand Electric Other Number of Ports/Ways 2 Pressure Rating 0.0 to 500 psi
Gauge Baerer Needle Valves. Performance similiar to Article 100 Needle Valve but gauge baerer type with manometer flange and bleed screw. Available in carbon steel and stainless steel DN 1/2 class API 3000. Data Sheet
Apr 28 2020 Needle Valves sometimes referred also as Plunger Valves are regulating valves and enable engineers to finely control and regulate fluid flow and pressure. Needle valves are similar to the globe valve in design with the biggest difference is the sharp needle shaped disk. Needle valve have a small port and a threaded needle shaped plunger.
