Operating pressures and flow rates up to 220 PSI and 12 GPM respectively. There are no elastomers lubricants or metals used in their construction. Available in PVC CPVC Polypro PVDF
Nov 07 2018 I have been locking for a electric controld needle valve and wonder if any of you no where till find one. The reason is till be able till control the orefies on my lm still from the ground cos its 3 5 meters up. I have a solenoid valv at the outlet but want to be able till set the reflux speed at different amounts in the process manualy.
Single needle drives. With the single needle valve SNV cascade injection moulding through the sequential closing and opening of the needles is possible. With an electric drive the step motor corresponds to the single needle valve. Up to 16 step motors can be controlled with extreme precision with the DPE control unit.

Aug 26 2019 The virtue of the needle valve is due to the vernier impact of the proportion between the length and diameter of the needle or the diameter difference between the needle and the seat. Needle valves can also be used in vacuum systems at low pressure when accurate control of gas flow is needed such as filling gas filled vacuum tubes gas lasers

Mar 09 2020 Flow controls Fig. 1 23 are adjustable orifices with an integral check valve to permit flow speed control in one direc tion only and reverse flow with minimal restriction. The most common flow control used is a needle valve integrated into a fitting. A bypass check valve will also be integrated in the fitting to permit free reverse flow.
Oct 13 2015 Needle Valve. Needle valve like a part of the big valve family continues to be playing a huge role in progressively and ultimately turning off the movement of liquid. Different needle valves are utilized to control the quantity of a

Series 92 Quarter Master Chief. The Series 92 electric actuator is our primary electric actuator for most butterfly valves and our larger ball valves as well as multi turn diaphragm and gate valves. Features include 2 SPDT switches output 400 in/lbs2000 in/lbstorque conduit 1/2 NPT.
When the valve is 60 open it will pass 2.091 m³/h an increase of 48 over the flow of 1.414 m³/h when the valve is 50 open. It can be seen that with a constant differential pressure for any 10 increase in valve lift there is a 48 increase in flowrate through the control valve.
The needle valve is able to do a linear manoeuvere also in a presence of relevant partialisation degree although high inlet pressure and big exercise difference of pressure. The needle valve controls the water flow rate through the axial movement of a shutter operated by a connecting rod and crank mechanism.
Needle Valves EM Technik Series 5L. Needle valve features ultra precise flow control for critical high purity and aggressive fluids. The needle tip is integrated into the PTFE diaphragm. Ideal Applications Include Gas and Liquid Flow.
