'PRIME' Needle valves are made for various operating pressure and temperatures. Looking at ever increasing demand and variety of applications, we have developed special purpose valves for instrumentation and flow control application.
DESIGN: Needle valves are also known as isolation valve, shut off valve or regulatory valve. Rotating angle tipped spindle, which in turn moves axially over the orifice seat, controls flow of the fluid. At the lower most position or closed position of the spindle, inlet orifice is completely blocked and thus isolates the fluid flow. In open condition Teflon or Grafoil packing seal restricts the leakage from the bonnet end.

The NV-30 series is a precision adjustable flow control used in pneumatic and fluidic systems. Nickel plated brass construction provides excellent corrosion resistance, and a clean and bright appearance. Flow control needle has 7 to 8 turns of precision adjustment, and maximum flow approximately equal to a 0.025" orifice. Unique laminar flow design ensures sensitive, repeatable control. Perfect for use in application requiring precision gas metering, and circuit speed or sequencing control.

Gate Valves and Needle Valves
Speed and flow can be regulated by a sf gate valve (aside from any dependence on pressure differences or viscosity). This is carried out by means of the coned seal which can be raised or lowered by the spindle. The further the spindle is raised, the greater the passage and hence the flow.

The MV-13 Manual PFA Needle Valve is designed for high purity or aggressive chemical and gas applications. The design utilizes a molded high purity PFA body and stem as the only wetted components. The stem sealing area is precision machined for smooth, consistent flow. A PTFE ferrule assures a leak tight seal between stem and body. A PFA stem stop prevents removal of stem from body during operation. The MV-13 is available in straight through and angle configurations, several orifice sizes, and numerous end connections.
FEATURES:
* One piece PFA stem/handle and bodies provide high strength and corrosion resistance
* PFA stem stop provide a safer operation
* Angle and straight through configurations, with numerous end configurations, including Parflare, reduces connections, mounting space, and overall cost

The F-2822 Series Needle Valves are ideal for instrumentation and industrial applications. The fine angle of the needle allows for the precise control of flow, which is restricted in both directions. The Needle Valves are adjustable from 0 to the equivalent flow of a 0.025” orifice and can be provided for inline installation or panel mounting.
Two models are available: The standard glass filled nylon model is available with straight ports for 1/16” I.D. tubing or barbs for 1/16” and 1/8” I.D. tubing. The glass-filled polypropylene model is beneficial for those applications where chemical resistance is a concern.
Both models can be supplied with a nickel-plated brass or stainless steel needle. The needles are available with a screwdriver slot adjustment or knurled knob. Buna-N, Viton, or Ethylene Propylene o’rings are available.

This type of valve is actuated by pressure acting on a piston or diaphragm. The fluid is usually neutral e.g. air, water, hydraulic oil. The pressure range varies and is specified accordingly in a data table.
"Normally Closed" (N/C) valves of this type remain closed under spring pressure, when de-activated.
"Normally Open" (N/O) valves of this type remain open under spring pressure, when de-activated.
When pressure is connected to port "Z" the valves open or close according to type.
A separate 3/2 pilot valve is used to supply pressure to port "Z", it is mounted either directly on the actuator or remotely.
In some cases a 4/2 or 5/2 pilot valve will be required. The main valve position can be N/C or N/O. The basic position is determined by connecting the pilot valve output lines accordingly. (The direction of flow is usually indicated by an arrow or shown schematically on the body).

The new ODE 21IA series is characterized by the angle seat body in stainless steel AISI 316, as all the components in contact with fluids. The angle seat specific body design allows to maintain the fluid flow extremely stable in order to guarantee a high flow values. The auto positioning floating shutter system and the Teflon ring guarantee good seal and reduced leakage over time. Moreover the particular configuration makes the valves resistant as well against fluids with abrasive and chemical contaminants. The standard configuration with flow in direction under shutter allows the execution anti water hammer. It’s available on demand even the version with flow above the shutter for application with gasses and steam.

The design of this double valve type is distinguished by two crossflow passages and special valve poppet and spool elements which provide the valve's unique flow characteristics. Two pressure switches are mounted on an adaptor and measure the pressure in the crossflow passages of the main valve. In normal operation the two valve elements move simultaneously and the pressure switches send a matched pair of signals to the control system. If there is a malfunction and the valve elements do not move simultaneously, the pressure switches send an unmatched pair of signals, the control system switches off the valve and prevents any further valve operation. Therefore, the two pressure switches, when correctly connected to the safety circuit, carry out a reliable monitoring function which is in full accordance with the requirements of EN 692.

A Y-Globe valve is an in line valve that is typically used to isolate or control medium flow.
Y Globe valves offer the perfect balance between flow and sealing requirements. The flow control characteristics are much better than a globe valve, while the zero leakage sealing performance far excel that of a ball valve.
It can be provided as a standard Y Globe valve or as a special control valve for severe service applications. They are widely used in Plastic and Polymer Industry as well as control variants in the Petrochemical, Chemicals, mineral processing and Refining industries.
The SchuF Y Globe valve is unique in respect of its flexibility, high Cv and reliable performance.
