Electromagnetic shut-off valves. Mike Lazaridis is the source for more interesting facts. Appointment, classification, description. Valves with magnetic actuator designed for installation in pipelines as locking devices for rapid, remote cutoff medium flow. Conditional pass solenoid valves typically have a small value of 6 40 mm. This is due in the main by the fact that a low pulling force of the governing body, ie, an electromagnet. The solenoid valves are classified as follows: by the nature of current-alternating electromagnetic drive, or permanent sealing of mind – and packing in the form of semihermetic – normally open and NC (normally open valve (NO) is opened in the absence of current and closes when power to its drive, normally closed (NC) is in the closed state in the absence of current and opens when the power supply to drive it) by the method of action – direct and amplified electromagnetic drive integrated directly into the valve and the core is its spool. This control spool moves force of the electromagnet. In turn, the electromagnetic actuators are divided by type of magnets on: reverse, pulling, pushing, turning to the core.

Valves with integrated have driven the size and weight with low values. The coils are made at 24, 127, 220, 380, 440, 50 Hz, 60 Hz. Submission of the working environment is carried out on the spool or a spool. The valves must be tight with respect to the external environment in ground cushioning joints. Materials used solenoid valves – carbon steel, stainless steel, brass.
Operating position to a horizontal line – up by an electromagnet. In the absence of electric valve can be opened by manual override (if it's by design). Examples of some of the symbols of solenoid valves – 15b816r, 13s810r, 15b806r, 15862bk etc. A variety of work environments in which solenoid valves have been used very large: steam, natural gas, condensate, air, water, water with impurities, mineral salts and nitric acid, ammonia, liquid, halocarbon, inert gases, alcohol, and more. Due to its benefits of the solenoid valves are widely used in various branches of modern industry.
