New angled bodied solenoid valve from Alcon increase flow rates and reduce problems
Solenoid valve glands are designed to be maintenance-free, and 316 stainless steel is used in the body construction offering maximum internal and external protection form liquid and gases.
Designed for water, steam and corrosive fluid applications, Alcon has introduced the ASAST series of 316 stainless steel valves, offering improved life particularly in high temperature process applications. By directing the flow of fluids and gases under the valve seat, the angled body design promotes higher flow rates while eliminating traditional problems associated with water hammer, helping to prolong the operating life of the valve and ensuring a smoother delivery of fluid.
Alcon has applied over 50 years experience and used state-of-the-art materials in order to maximise performance and minimise maintenance of the new extreme environment ASAST valves. Inert to all but a few obscure substances a PTFE (Teflon) is used in the main seal to maintain performance across a wide range of temperatures, allowing the valves to reliably control fluids and gases from –200 OC to +180OC (-328 ° F to +356 ° F).
Taking into account any future maintenance operations at the design stage, Alcon have angled the main body of the valve to reduce the height of the unit. This allows engineers in compressed air, packaging, water and paper processing industries to develop smaller, more compact systems with additional room for maintenance operations. Ease of fitting and maintenance has been further improved by the introduction of an optical indicator, which allows easy identification of valve position; the body of the valve can also be rotated 360 O for quicker status checking.
Remote control is achieved via 13mm BS21 or NPT port connections for single spring return or double acting compressed air piloting arrangements. Alternatively the solenoid valve bodies are designed for the attachment of Alcon 31 Series solenoid pilot valves for electronic operation. Control inputs can come from 12v, 24v, 48v, 110v DC sources or 24v, 110v, 120v, 220v, 230v, 50/60HZ AC supplies . The valves cater for pipe sizes from 13mm (1/2") to 50mm (2") and are available with NPT, BSP, Butt or Socket Weld fitting arrangements, high flow rates of up to 52.8Kv are possible using the 50mm (2") unit. Alcon ASAST series valves function reliably in external temperatures ranging from -10 ° C to +60 ° C (+14 ° F to +140 ° F).
Symptom: short coil life
Diagnosis: Excessive heat is typically the cause of short coil life. Heat can be generated by media temperature, ambient temperature, excessive voltage, or an incomplete magnetic circuit.
Remedy: Care should be taken to specify a coil insulation system capable of withstanding the various operating temperatures. Never energize a coil when it isn't in the plunger tube.
Most solenoid coils today are epoxy or plastic encapsulated. However, if a tape-wound coil is used, moisture or dust may cause premature failure.
Altogether, solenoid valves are reliable and easy to maintain. If they are installed properly and inspected thoroughly in a regular maintenance program, they should operate efficiently and with few problems.

Calculate the magnitude of the magnetic field?
A small diameter, 79.0 cm long solenoid has 283 turns and is connected in series with a resistor of 164 Ω. Calculate the magnitude of the magnetic field (in T) in the middle of the solenoid when a voltage of 52.0 V is applied to the circuit and the current is steady. (Assume the solenoid has no resistance.)
The magnetic field in the solenoid is μo*n*I where n = N/L and I = V/R
so B = μo*N/L*V/R = 4πx10^-7*283/0.79m*52.0/164 = 1.43x10^-4T
