Application
Regulating / hand expansion valves are regularly used at the evaporator in liquid circulation systems. Also these valves are used in liquid circulation systems before a vessel. Here they prevent high pressure fluctuation in the vessel when fluid stream into the vessel.
In order to function as a regulating valve, each NB size has a 'valve-cone' has a unique form. The shape of the cone and the percentage of opening of the valve determines the m3/h flow and/or pressure drop. Use the Revalco selection software to determine the correct valve.

Style 175 GTO Gas Valve
- Permanently lubricated at the factory for maintenance-free service
- Low operating torque - No plug "freezing"
- 100% shut-off; 360° turn or 90° Open Left operation
- Features a superior tamper-proof design
- No leakage to the atmosphere
- One valve covers full pressure range
Designed to meet the requirements of ANSI B16.33 1981, the Dresser® Style 175 GTO Gas Service Valve incorporates the same complementary sealing principles as the Style 175 meter curb valve, yet offers a rated working pressure to 175 psig. Each GTO valve is 100% factory-tested at high and low pressure while in a clear non-corrosive fluid.
Just as the Style 175 meter curb valve, the GTO is assembled at the factory and sealed against tampering by a spring loaded stainless steel retaining ring which cannot be removed with ordinary tools. It is tamper proof as specified in D.O.T. 192.363 Part C.
A plastic ring inserted between the retaining ring and bonnet, plus permanently lubricated port seals, assure low, uniform operating torque, preventing the plug from freezing to the body.

KOFLOC 2204
The KOFLOC Variable Primary Pressure Flow Controller MODEL 2204 SERIES is a control valve for precise control of minute gas flow and maintaining constant flow under fluctuating primary pressure (inlet), provided the secondary (outlet) pressure remains constant. This characteristic makes it a must-have preliminary valve in many flow control mechanisms. Constructed using high precision parts, the design of the MODEL 2204 SERIES transforms the rotation of the regulating screw to into linear motion of the needle without subjecting it to gaps and vibrations produced by the screw, to ensure stable and even control of minute flow.
FEATURES
♦ Excellent flow stabilization
♦ Clean construction
♦ Independent from supply pressure fluctuations
APPLICATIONS
♦ Scientific instruments
♦ Environmental analysis
♦ Atomic absorption spectrometry
♦ Gas chromatography
♦ R&D
♦ General industrial use

The Model 6N Needle Valves have been designed to give higher strength and integrity to instrument needle valves. Budenberg have incorporated a dynamic multi-ring gland system in the needle valve, which when combined with the anti blow-out back seating stem, guarantees resistance to all operating processes and pressures.
Low operating torques and high cycle life feature strongly in this unique Budenberg design, giving a "Low Cost of Ownership".
Key Benefits are:
Guaranteed Sealing with the minimum effort.
Over designed high strength adaptor threads combine with soft' parent metal bottom seal to give closure thread protection and ensures environmental safety.
Gland and stem leakage is a thing of the past due to the dynamic multi-ring gland system, combined with the anti blow-out back seating system
Swaged self centering non-rotating Duplex stem ensures. point positive seat closure under all conditions.

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).
