Air Check Valve Assembly (BCV/A) For Aspee Marut 3.5 L Hand Operated Compression Sprayer

Air Check Valve Assembly (BCV/A) 

Air check valve assembly (SKU / part code BCV/A) is a one‑way valve unit installed in the pump‑air‑vent system of the Aspee Marut 3.5 L hand operated compression sprayer. It allows air to enter the pump or tank chamber during the suction stroke while preventing back‑flow of liquid or air when pressure is built, ensuring quick and stable pressure build‑up for consistent spraying. The assembly typically includes a small chamber, a rubber or plastic seal, and a spring‑loaded check‑element that opens and closes automatically with handle movement, minimizing leakage and maintaining effective spray performance during pesticide, herbicide, or fertilizer application.
