A Check Valve Collar fitted inside a fuel injection pump helps to control the flow of fuel and maintain proper pressure within the pump. It is made from strong and durable material such as steel and incorporates the check valve mechanism, which allows fuel to flow in one direction while preventing backflow or reverse flow. Attributes:• Helps in maintaining the fuel pressure remains within the desired range• Hardened with Rockwell Hardness Scale value of 30N, indicating its resistance against deformationApplications:A Check Valve Collar allows fuel to flow from the pump inlet to the pump outlet, supplying fuel to the engine and preventing fuel from flowing backward, ensuring the proper direction of fuel flow.
