It is widely used across electronics, semiconductor, automotive, and laboratory industries for precise fluid control.\u003c\/p\u003e\n\u003ch4\u003eQ: How does the solenoid valve control the dispensing valve?\u003c\/h4\u003e\n\u003cp\u003eA: The solenoid valve has one air intake and two air outlets (normally open A and normally closed B). By selecting the correct port configuration — which varies by valve type (suction, plunger, diaphragm, or ejector) — it directs compressed air to move the cylinder piston up and down, controlling when and how much fluid is dispensed.\u003c\/p\u003e\n\u003ch4\u003eQ: What should I do if my dispensing valve drips after stopping?\u003c\/h4\u003e\n\u003cp\u003eA: Post-stop dripping is usually caused by excessive supply pressure or a needle with too small an inner diameter creating negative pressure. To resolve this, try replacing the needle with one that has a larger inner diameter, or reduce the supply pressure to slow the fluid flow rate. Both measures help reduce negative pressure buildup at the needle tip.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the body of this dispensing valve made from?\u003c\/h4\u003e\n\u003cp\u003eA: The valve body is constructed from aluminum alloy, providing a lightweight yet durable and corrosion-resistant build suitable for continuous industrial use.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
