Product Overview Of Flanged Solenoid Valves

Flanged solenoid valves are usually used in mechanical control and industrial valves to control the direction of the medium, thereby achieving on-off control of the valve. They can automatically open or close upon receiving electrical control signals, realizing on-off control or flow regulation of fluids in pipelines.

Application Fields Of Flanged Solenoid Valves

Flanged solenoid valves are widely applied in production and R&D departments such as textile, printing, chemical industry, plastics, rubber, pharmaceuticals, food, machinery, electrical appliances, and surface treatment, as well as daily living facilities including bathrooms, canteens, and air conditioning systems. They are mainly used for controlling corrosive liquids, ultra-pure liquids, edible liquid media, as well as corrosive gases, ultra-pure gases, and other gaseous media.

Working Principle Of Flanged Solenoid Valves

• Normally Closed (NC): When the coil is energized, the electromagnet core is attracted, the pressure relief hole opens, and the main piston is pushed by the medium pressure to open the main valve port, allowing medium circulation. When the coil is de-energized, the main valve port closes, and the medium flow is cut off.

• Normally Open (NO): When the coil is energized, the electromagnet core is attracted, the pressure relief hole closes, and the main piston is pushed by the medium pressure to close the main valve port, cutting off medium flow. When the coil is de-energized, the main valve port opens, and the medium circulates.

Key Features

• Corrosion Resistance: Most components are made of stainless steel or cast stainless steel, ensuring excellent corrosion resistance.

• High-Temperature Resistance: The electromagnetic part and seals are all made of special high-temperature resistant electrical materials and sealing materials, with effective heat insulation measures adopted.

• Wear Resistance: Rational material selection is adopted. The fluid lubrication effect is cleverly utilized between the valve cup and the guide sleeve, reducing wear.

• Reliability: Featuring a simple and compact structure, it integrates the advantages of direct-acting and pilot indirect solenoid valves, and can work reliably even under low pressure difference or zero pressure difference.
