Port Solenoid Valve

Solenoid Valves and How They Work

Obviously, valves operate in different mechanisms. Majority of valves can be manipulated by manually turning, but there are valves that operate by temperature or pressure. Manually operated valves are used in simple transport applications involving non-abrasive fluids like water and oil. This type of valve, on the other hand, is not used for large-scale applications using bulky pipelines. Large, automatic or power-driven valves are used instead.

 

Solenoid valves are examples of valves used for regulating high fluid flow. This type of valve consists chiefly of a solenoid and a long, flimsy loop of wire which produces a strong magnetic field when current is applied. The electromagnetic field turns the solenoid into a magnet that can create a controlled linear force. This refers to different transducers that convert electrical energy to mechanical energy.

 

Other important parts of a solenoid valve include piston, plunger, springs, and diaphragm. The piston is the metal tube that contains the plunger. The solenoid turns it into an electromagnet to pull up and to release the plunger inside. It serves as a dividing surface between the plunger and the coil. Except for the diaphragm, the piston is typically made of hard corrosion-resistant metal.

 

A solenoid produces a weak magnetic field that can pull the plunger up a bit. However, when applied with direct current, it creates a string magnetic force that can lift the plunger to a desirable elevation, which allows the fluid to flow through the ports. Large solenoid valves such as the Spence E5 Valve are made of huge coils that require a considerable amount of current to produce the necessary magnetism.

 

The plunger, on the other hand, is partly suspended within the piston through springs on both its ends. When current is applied to the coil, it moves up and pulls the diaphragm upward to allow fluid to enter the ports. When the source of electricity is shut down, the lounger travels back in place and covers the port. This device is employed in valves like the Spence E5 Valve.

The amount of fluid to go through the port is usually determined by how long current is applied on the coil. When the pipeline is closed and fluid is not flowing, the plunger is down and the power supply is shut down. This mechanism presents a number of advantages, including immediate response to fluid flow and does not require direct human intervention. This is why solenoid valves like Spence PRV are widely used.

Solenoid Valve - Product Cares

One-touch Fittings : SMC Solenoid Valve

The pitch of the SJ series piping ports (A, B etc.) has been set presuming the utilising of KJ series one-touch fittings. Therefore , when using fittings with an M3 or M5 port block assembly, there may be some interference between fittings, up on the type and size, so please use after checking dimensions in the product brochure for the pipe fitting being used.

1. Tube attachment/detachment for one-touch fittings

1) Attaching of tubes

(1) Take a tube having no failings on its edge and cut it off at a right angle. When cutting the tube, use tube cutters TK-1, 2 or 3. Don't use pincher, nippers or scissors, etc. If cutting is done with tools apart from tube cutters, there's the danger the tube may be cut diagonally or become flattened, etc, making a safety installation impossible, and causing issues such as the tube pulling out after installation or air leakage.Also leave some additional length in the tube.

(2) Grasp the tube and push it in slowly, inserting it securely all around way into the fitting.

(3) After inserting the tube, pull on it softly to ratify that it will not come out. If it's not installed securely all of the way into the fitting, this can cause issues such as air seepage or the tube pulling out.

2) Detaching of tubes

(1) The 4 (A) and 2 (B) ports use the KJ series, so that tube can be removed by pressing on part of the release bush. Nonetheless for the 1 (P) and 3/5 (E) ports, please press the
release bush equally as before.

(2) Pull out the tube while holding down the release button in order that it can not come out. If the release button will not pressed down satisfactorily, there will be increased bite on
the tube and it will get more tough to pull it out.

(3) When the removed tube is to be used again, cut off the portion that the has been gnawed before reusing it. If the chewed portion of the tube is used as is, this may cause bother look like air leaking or difficulty in remotion the tube.

Sprinkler System Help!! Vaccuum Breaker Issue?

Trying to get the sprinklers going, they were winterized last fall by a professional. I can hear the solenoids working and every zone is getting the necessary 24V. The controller is working and obviously the fuse isnt blown. I even played with the 2 breaker valves in all combinations and cant get anything to flow to the sprinklers, just water out of the one test port in the breaker. This has to be a breaker issue. Maybe theres a pocket of pressure or a stuck spring, Im not sure. Any ideas on how to trouble shoot, am I missing something obvious????

Yes the water is turned on, Im plenty wet already from playing with the valves!

Its probably a valve has gone bad. The diaphragms go bad and lock in place.

Even if you hear the solenoid clicking it does not mean anything. These sites may explain it.
