Pilot Valve

The basic concept of solenoid valve

Solenoid valve is used to control the direction of fluid based automation components, belonging to the actuator; often used for machine control and industrial valves above, to control the direction of the medium, so as to achieve the control switch on the valve.

Solenoid valve in a closed chamber, in different locations with holes, each hole leads to a different pipeline, valve chamber in the middle, both sides are two electromagnets, which face the magnet coils body will be attracted to which side, solenoid valves by controlling the body's movement to a different file live or leaked oil discharge hole, and into the hole is always open, hydraulic oil flows to different hoses, then the pressure to push through the oil tank piston, piston rod has driven, piston rod drive mechanism moving. This electrical flow by controlling the electromagnet to control the mechanical movement off.

New multi-function solenoid valves: Install the pipe, both manual functions, eliminating the need for three manual valves, online maintenance, significantly reducing costs. Medium viscosity adjustable scope: regulation allows gas, water, oil general, convenient purchasing, storage, installation and maintenance. Valves open and close time is adjustable: meet a variety of different requirements, to effectively prevent water hammer damage. Valve opening can be adjusted: the maximum and minimum opening can be preset to improve control accuracy. The main valve can compensate for wear and tear:: extend valve life, stand the test of time.

The structure of electromagnetic valve principle: electromagnetic valve skillfully pilot solenoid valve, manual valve and throttle combination in one of the pilot valve to accept signals switch the main valve is driven. Adjusting screws A, B medium viscosity can be adjusted the scope and main valve switching time, and can be compensated after the main valve wear. Pilot valve needs maintenance, just tighten the adjusting screw bolt B and isolation of C, can be removed, and can be used to manually screw operation. The screw can also be used to control solenoid valve when the preset maximum or minimum flow.

What are the main solenoid valves features it, the following were introduced.

Leakage blocking must, within the leak easy to control, use of safety. Internal and external leaks are endangering the safety factor. Other controlled valve stem out usually by electrical, pneumatic, hydraulic actuator control valve of the rotation or move. This should solve the long-term action outside the dynamic seal valve stem leakage problems; only solenoid valve is sealed with a magnetic force on the septum in the electric magnetic valve core inside the casing to complete, there is no dynamic seal, so easy to block leakage must . Electric torque control valve is not easy, prone to internal leakage, and even pull off the stem head; solenoid valve within the structure of type easy to control leakage, until reduced to zero. Therefore, the use of special safety valve, particularly suitable for corrosive, toxic or high temperature media.

System is simple, then take the computer, low price modest. Solenoid valve itself is simple, the price is also low, compared to control valve actuators, and other types of easy installation and maintenance. More significant is the automatic control system consisting of much simpler, much lower price. As the solenoid valve is a switching signal control, and industrial computer connection is solenoid valves very convenient. In today's widespread use of computers, an era of declining prices, the electromagnetic valve is even more obvious advantages.

Action Express, power tiny, lightweight form factor. Valve response time can be as short as a few milliseconds, even pilot-type solenoid valve can be controlled in several milliseconds. As the self into a loop, other than the automatic control valve more responsive. The proper design of solenoid valve coil power consumption is very low, is energy-saving products; can do just trigger action, automatically maintain the valve position, usually is not power. Solenoid valve shape, small size, both to save space, and lightweight appearance.

Regulation accuracy is limited, apply to limited media. Solenoid valve is usually only switches two states, spool position only at the two limits can not be continuously adjusted, (trying to break a lot of new ideas, but also are in the pilot trial phase), so regulation accuracy is also subject to certain restrictions. Solenoid valve on the media have a higher cleanliness requirements, including granular media can not be applied, in the case prior to filter impurities. In addition, the viscous medium can not be applied, and, to a specific product for a relatively solenoid valves narrow range of medium viscosity.

Models varied widely used. Notwithstanding the inherent electromagnetic valve, the advantages are still very prominent, so we designed a wide range of products to meet different needs, and used widely. Solenoid valves technology advances are also centered on how to overcome the deficiencies, how to better play to existing strengths and expand.

Pressure Relief Valve $81.25 High Quality Content by WIKIPEDIA articles A pressure relief valve is a safety device that relieves in case of overpressure in a vessel or piping. The generic terms are pressure relief valve (PRV) or pressure safety valve (PSV). Main types of pressure relief valves include: Relief valve (RV) automatic system that relief by static pressure on a liquid. It specifically open proportionally with pressure increasing. Safety valve (SV) automatic system that relieve static pressure on a gas. It specifically opens almost straight to full lift after a pop sound. Safety relief valve (SRV) automatic system that relief by static pressure on both gas and liquid. Pilot operated safety relief valve (POSRV) automatic system that relief by remote command from a pilot on which the static pressure (from equipment to protect) is connected. Low pressure safety valve (LPSV) automatic system that relief by static pressure on a gas. The pressure is small and near the atmospheric pressure. Vacuum pressure safety valve (VPSV) automatic system that relief by static pressure on a gas. The pressure is small, negative and near the atmospheric pressure.
