Automatic calibration by simply operating the switch Equipped with communication module, so it is possible to monitor the travel status of the positioner from a distance When an abnormal operation occurs, a warning will be issued to the control room Functions of Explosion Proof Electro-pneumatic Digital Positioner The GK2300LSdF00GO series control valve positioner has the on-site Class II explosion-proof function, and the performance and installation are reliable. Low power consumption / low air consumption, built-in lightning protection module, can avoid damage to the positioner due to lightning strikes. Built-in HOERBIGER piezoelectric valve technology, long service life, using two-wire 4- 20mA standard signal, the valve position setting value is obtained through A/D conversion; at the same time, the actual valve position signal is obtained through the position sensor; both are calculated by the control software Processing, so as to control the air intake and exhaust of the pneumatic actuator, and drive the valve position to reach the set point. Features of Explosion Proof electric valve positioner Electric structural principle GK-2300, avoiding the traditional locator output due to the shock caused by the mechanical properties, such as zero drift unstable performance weaknesses, so that the control valve is more stable. German piezoelectric valve action time <20ms, high positioning accuracy, reduced valve opening due to the shock caused by inaccurate positioning, improve valve control accuracy. GK-2300 valve characteristic curve correction and sub-process control function, scalable control valve applications. GK-2300 has a lightning-enabled smart valve positioner. GK-2300 uses a special design, the internal pressure of the formation of microseismic, isolated on the outside air infiltration chamber, more adapted to complex and harsh working conditions. GK-2300 uses no mechanical electrical conversion unit, fully sealed structure, the German piezoelectric valve MTBF up to 20 billion times the switching frequency, high reliability. GK-2300 comes with the oscillation phenomenon flow regulating device can be precisely controlled by the base knob actuator input to the air flow, thus eliminating the small capacity of the actuator. GK-2300 comes with three off to secure his position, with no external solenoid valves, lock valve and other accessories can achieve self-protection valve interlock switch output or switching valve action to avoid failure and jeopardize production. GK-2300 using the world's latest technology and the German electrical conversion piezoelectric valve, the steady-state air consumption of less than 36 liters / hour (conventional positioners 400 liters / hour) of electricity a year could save more than 1400 degrees (petrochemical energy calculated to international standards). GK-2300 may, within one minute self-tuning zero and stroke tuning scene without external signal source; high volume applications, you can download the communication parameters; All operations completed just three buttons. GK-2300 7 character LCD with double rotating opening and the optional pressure gauge shows clearly intuitive reaction site conditions. GK-2300's unique emergency mode, you can not open the case in the field of direct manual operation of the closed shell valve.

Geko has three types electripower actuator, from linear actuator, quarter-turn actuator to intelligent integral actuator which can meet your different needs. They have been preferred for their reliability and durability for decades. We specialize in partnering with you while providing perfect actuation solutions. Different explosion proof electric actuator Types 1,GKL-Series flow control valve electric actuator is mechanical device that moves in a straight line to complete or start a process. 2,GKSA-Series electric actuator is intelligent integral electric actuator. 3,GKQ-Series electronic is a type of actuator that convert electric energy into a rotary force, and it can only make a 90 degree turn(a quarter-turn). Electric Actuators Working Principle An actuator is the component of a valve that is responsible for moving and controlling the valve, for example by opening a valve. To drive an electric actuator requires a control signal and a source of energy. Electric voltage or current is available to be the control signal, but the main energy source must be an electric current. When it receives a control signal, an actuator responds by converting the source's energy into mechanical motion. GEKO Valves & Controls, born in Germany, is a well-known professional electric actuator factory and valve maker, we provide china industrial valve, electric actuator manual, linear actuator 12v 600mm, industrial valve, valve sale and etc. For electric actuator application or electric actuator selection, please feel free to contact us!

Geko cryogenic needle valve are commonly designed for the applications at very low temperature, such as the storage or transportation of liquefied natural gas, liquefied petroleum gas or liquid nitrogen or other medium. Geko cryogenic valves are offered in ball, globe, check, and relief configurations. Geko cryogenic valves can be used in systems for mediums like cryogenic nitrogen, hydrogen, argon, helium, and oxygen. Manufacture Suitable Cryogenic Valves for You Cryogenic Ball Valves Cryogenic ball valves are rather efficient when there are high sealing requirements. However, the seals and the ball body are easy to wear. Therefore, they are not recommended to use in the restricted fluid system. Cryogenic Check Valves Cryogenic check valves could keep the pressure at a certain point to prevent fluids back at low temperature. Cryogenic Globe Valves Cryogenic globe valves could provide effective sealing for a long time. However, they are not suggested to apply in a high fluid system. Cryogenic Relief Valves Cryogenic relief valves are mainly applied in liquid oxygen converters in cryogenic systems. The pressure could be set to adapt to various requirements. What Are Cryogenic Valves Used For? Cryogenic valves are specially manufactured and used for those applications at low temperature. which include: various gasseparation, aerospace applications; medical research etc. Cryogenic valves are used in the production, transport and storage of liquefied gases. because the gas is easy to deal with in the liquefied condition. FAQs of Cryogenic Valve Q Why do cryogenic valves have long stems? Since working materials under low-temperature maybe toxic, flammable or explosive. Therefore, we should make sure the particularity of the safety requirements. Cryogenic valves with long stem could reduce the heat to the inside transferred from the outside. Q What are cryogenic valves used for? GEKO Valves & Controls, born in Germany, is a well-known professional cryogenic valve factory, we provide china industrial valve, cryogenic valves pdf, liquid nitrogen solenoid valve, cryogenic valve design, industrial valve, valve material and etc. For cryogenic valve applications or cryogenic valves definition, please feel free to contact us!

AWG waveguide (AWG) device is a dispersive passive device and planar waveguide device. It is based on the planar light – wave circuit (PLC) technology and the basic optical principle of linear interference between different wavelengths of light. At the transmission end, arrayed waveguide grating can compound many wavelengths of light into a single optical fiber, At the same time, at the receiving end, these lights can also be separated again. A grating formed by a group of arrayed waveguides with equal length difference, which has the ability of wave division. This means that if each channel uses light with fine microwave length difference, the light of many channels can be carried by a single optical fiber, and only negligible signal crosstalk, so as to improve the propagation efficiency of optical fiber network. Different Types of AWG 100G HEAT-FREE AWG (40 CH) Arrayed Waveguide Grating3 17-CH O BAND, 1550GH2 DWDM AWG As one of arrayed waveguide grating manufacturers, we have types of related products for sale and the arrayed waveguide grating price is affordable, anything you need, please contact us.
