DELCO Direct Pull Diaphragm Stainless Steel Gas Flange Solenoid Valve Normally Closed/Open

Direct pull diaphragm stainless steel flange solenoid valves use electromagnetic suction to push the diaphragm open or closed under low or no pressure conditions. This feature enables these valves to be effectively regulated even in unpressurised or low-pressure environments. Available in normally closed or normally open types, they are widely used in pipelines, water treatment, natural gas, chemical, petrochemical, electric power, mining, food, municipal, machinery and equipment, electronic industry, urban construction and other fields.

    Introduction to diaphragm solenoid valves:

    The use of advanced manufacturing technology and precision machining technology ensures that all parts of the valve meet industry standards for reliable quality and stable performance characteristics. The valve is operated by electromagnetic suction control of the diaphragm, allowing fast and reliable valve control. There are two types available: normally closed and normally open.

    ● Normally Closed (NC) Solenoid Valve: When not energised, the valve stops the flow of fluid. When energised, the valve opens to allow fluid flow. These valves are ideal for safety systems and water supply control.
    ● Normally Open (NO) Solenoid Valves: In their default state, they allow fluid flow. When energised, the valve closes, stopping fluid flow. They are commonly used in cooling and ventilation systems.

    Technical Parameters:

     

    Applicable media: Civil Gas, Stem, Air Oil. Hot Water, Water, Chemical.
    The diaphragm is made of a soft material such as rubber or polymer for good sealing and corrosion resistance
    The valve body is made of stainless steel metal to hold the diaphragm and solenoid coil.

    The features of Direct pull diaphragm stainless steel flange solenoid valves

    ● Fast action response: The electromagnetic drive mechanism allows the valve to open or close quickly, providing a fast response time for fluid control.
    ● Wide applicability: Suitable for control of various liquid and gas media, with strong versatility.
    ● High reliability: Straight pull diaphragm type, simple structure, no wearing parts, so it has high reliability and durability.
