The Magna Flow Control Valve with an easy to read micrometer dial offers an amazing 1100 precise set points to accurately control flow of gases or liquids. The extremely high CV of the Magna Flow control valve enables very high flows for whatever media is being controlled, up to 200 PSIG pressure or full vacuum. Linear flow characteristics provide easy to set and precise metering of gases and liquids for almost any application where accurate results are required.
Available in either light weight impact resistant nylon or clear polycarbonate construction, the Magna Flow Control Valve offers superior strength and corrosion resistance, making it ideal for use in hundreds of different applications. Simplicity of construction, with removable top and bottom caps, provides easy disassembly for cleaning or maintenance without removing the valve from service. Proven O-ring seals provide a positive zero tight shut-off. Replacement of seals, if required, is quick and easy because disassembly is simple and fast. The Magna Flow Control Valve offers all these features at a very affordable price.

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.

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).

ASCO/JOUCOMATIC has developed a wide range of valves for all fluids, whether neutral or aggressive, made out of brass, bronze, cast iron or 316L stainless steel.
Reliability is ensured by:
* A monobloc rod, with stainless steel from the reed to the piston
* Guidance by 2 extra-large PTFE bearings.
Pilot solutions: solenoid valves on valves or mounted on subbases and valve islands.

Hayward Needle Valves are used for accurate metering of fluids. Turning the thumbwheel moves a tapered piston into the PTFE seat to control the flow down to a few drops per minute. Precision molded,fine pitched stem threads permit this very fine metering flow control.

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.

Directional valves direct the flow of fluid, at the desired time, to the point in a fluid power system where it will perform work.
These valves may be classified in several ways:
- type of control
- the number of ports in the valve housing
- the specific function of the valve

No Pressure Differential Design:
For maximum application flexibility these heavy duty solenoid valves have been designed so that no pressure differential is needed for them to operate reliably. Their unique design eliminates problems such as sticking and "chattering" due to system pressure differentials that can affect ordinary solenoid valves. And their performance is not effected by downstream restrictions caused by nozzles, flow meters or other equipment. This is a real benefit in these types of applications. The valve will operate with up to 40 PSI of backpressure and up to 120 PSI of inlet pressure. There are no minimum pressure requirements.
Normally Closed Operation:
When electric power is applied to the solenoid, the electromagnetic coil is energized, opening the valve. When the coil is de-energized, the valve closes.
Innovative Coil Design:
Unique in design, the valve coil rectifies AC current to DC current, resulting in lower coil operating temperatures than other plastic solenoid valves. This permits the coil to be rated for 100% continuous duty applications. Thus, the valve can be left in the open position indefinitely or it can be cycled continuously with no coil damage.
Unique Seal Cartridge:
Hayward Solenoid Valves feature an easy to replace seal cartridge. No fumbling with small parts and o-rings to replace worn seals. Just install the one-piece cartridge containing the plunger assembly and all of the seals.
Corrosion Resistant Coil:
The powerful coil assembly and electronics are completely encapsulated in a molded polyester housing, resistant to the harsh corrosive environments to which solenoid valves are often exposed.

In most refrigeration applications, in order to automatically control the flow of fluids in a system, it is necessary to be able to start or stop the flow in the refrigerant circuit. An electrically operated solenoid valve is usually used for this purpose. Its basic function is the same as a manually operated shutoff valve, but it can be positioned in remote locations, and may be conveniently controlled by simple electrical switches. Solenoid valves can be operated by a thermostatic switch (the most common in refrigeration systems), float switches, low pressure switches, high pressure switches or any other device used for making or breaking an electric circuit.
