It connects via a 4-point external screw thread and operates at pressures between 0.02 and 0.8 MPa at normal water temperatures. The valve is designed for one-way flow and uses a plastic body with a copper joint. It is suitable for water medium only, offering a straightforward way to control flow in small-bore tube setups. The DC12V coil and pilot mechanism allow electrical on\/off control when paired with a suitable power supply. This valve is a practical component for applications requiring a compact, normally closed stop function.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"A04 DC12V water solenoid valve, normally closed pilot type, 4-point external screw, plastic body, copper joint\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/2854\/2025-10-16\/original-image\/23509379865214.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe A04 valve combines a pilot-type operating mechanism with a normally closed design, meaning the valve stays shut when de-energised. Its external screw connection and 4-point nominal diameter suit specific tube fittings. The construction uses a plastic body and a copper joint, giving a lightweight assembly with a metallic threaded interface.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe valve body is made from plastic, which keeps the overall weight down while providing the housing for the internal pilot mechanism. The joint is copper, forming the external threaded connection point that meets the water line. This combination of materials is stated for the A04 model and is intended for water medium use. No additional seals or coatings are specified in the source data.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eThe nominal diameter is 4 points outside, which corresponds to the external tube size in millimetres. The connection form is external thread, so it screws into a matching port. The valve operates within a pressure range of 0.02 to 0.8 MPa and at normal water temperatures. These specifications should be checked against your system before installation to ensure compatibility.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"A04 DC12V water solenoid valve, normally closed pilot type, 4-point external screw, plastic body, copper joint\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/2854\/2025-10-16\/original-image\/636353840727.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThis solenoid valve is designed for water medium and one-way flow, making it suitable for simple stop\/start control in low-pressure water lines. Its DC12V pilot-type operation allows it to be used in electrical control circuits where a normally closed valve is required. The compact 4-point external screw connection fits specific small-bore setups.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eIn professional or automated systems, this valve can serve as a stop valve for water when powered off. The normally closed function provides a fail-safe stop if power is lost. It is compatible with water only and should be installed according to the one-way flow direction. The pressure and temperature limits must be respected for reliable operation.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eFor home projects involving water control, this valve can be used in DIY setups such as automatic watering or simple flow control, provided the system matches the 4-point external thread and DC12V power requirement. It is not intended for aggressive chemicals or high-temperature water. The plastic body and copper joint are suited to normal water conditions as specified.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"A04 DC12V water solenoid valve, normally closed pilot type, 4-point external screw, plastic body, copper joint\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/2854\/2025-10-16\/original-image\/829243341823.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe A04 valve offers a specific set of specifications for a narrow application: DC12V, normally closed, pilot type, 4-point external screw, and a 0.02–0.8 MPa range. Its value lies in matching these exact requirements. The plastic and copper construction keeps the component lightweight while providing a threaded joint.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eWith no user-serviceable parts listed, maintenance is limited to keeping the valve within its stated operating conditions and ensuring the water supply is clean. The normally closed design means it remains shut when unpowered, which can reduce the need for additional shut-off devices in some circuits. No specific maintenance schedule is provided in the source data.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eThis valve is a suitable choice when you need a DC12V, pilot-type, normally closed water solenoid valve with a 4-point external screw connection. The pressure range of 0.02–0.8 MPa covers many low-pressure water applications. The plastic body and copper joint are the stated materials, and the valve is for water medium only. Verify your system's thread, voltage, and pressure to ensure a correct fit.\u003c\/p\u003e","brand":"t0zkis-0a","offers":[{"title":"default","offer_id":58950343459147,"sku":"CJJZGJMG00018-default","price":19.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/5778\/2347\/files\/23509379865214.webp?v=1792652627","url":"https:\/\/homeenjoy.us\/products\/water-solenoid-valve-a04-dc12v-pressure-normally-closed-pilot-type-4-tube-external-screw-plastic-body-copper-joint-one-way-stop","provider":"Homeenjoy.us","version":"1.0","type":"link"}
