Solenoid Valve For Air & Gas

SOLENOID VALVE FOR AIR AND GAS SLOW OPENING AND FAST CLOSING, for air and gas slow opening and fast closing

VML

Safety solenoid valves for air and gas slow opening and fast closing
The VML type valve is a safety valve that is normally closed, with fast or slow opening and adjustable rapid section for initial gas flow. When not in working position the spring works on the disc keeping the gas passage closed. When the coil is powered the valve opens rapidly in the first section of the flow, then slowly, with adjust-able speed. When power is switched off the valve rapidly shuts.
This type of device is suitable for gas and air blocking and adjusting controls in atmospheric burners or fan-assisted burners, in industrial kilns and in all gas equipments which use gas solenoid valves (qualified for continuous service – 100% ED).

Before connecting the power supply, the user should create positive ventilation more than 5 times the enclosure volume for air exchange. The user must install the ultrasonic flow meters wiring in a safe area that  would not cause sparking or arcing due to short circuiting or wire breakage. Cables and wires should be installed through explosion-proof conduit. Explosion-proof threaded conduit unions should be used between the wired conduits, conduits and junction boxes. The available thread. engagement  into the fitting should be more than 5-6 threads. When flexible connections are needed, ex-proof flexible cable conduits can be used. Material :Die-cast al uminum Explosi on-proof rating : Exd Ⅱ BT4 Electrical   interface : 4×G1/2 ″ Wmm: 0.15 Ra:  3.2  Installation Site Selection When selecting a measurement site, it is important to select an area where the fluid flow profile is fully developed to guarantee a highly accurate measurement. Use the following guidelines to select a proper installation site: Choose a section of pipe that is always full of liquid, such as a vertical pipe with flow in the upward direction or a full horizontal pipe. Ensure enough straight  pipe length at least equal to the figure shown below for the upstream and down stream transducers installation. Clamp-on Transducers Installation Methods  Clamp-on Ultrasonic Flow meters are installed simply by applying coupling compound on the bottom of the transducers and strapping them to the outside of the pipe. SiteLab Clamp on Ultrasonic Flow meters are internationally known for their simple and convenient installation and low maintenance characteristics.
