Key Features

• Solid Brass Construction: — Brass body provides corrosion resistance and durability in fuel and fluid line applications, standing up to the demands of continuous generator operation.
• Locking Mechanism for Controlled Flow: — The integrated locking feature prevents accidental valve actuation, helping maintain safe, controlled fluid management during service and operation.
• 1/2" FNPT Threading for Direct Connection: — Female NPT thread sizing allows this valve to thread directly into existing ports without adapters or modifications to the plumbing circuit.
• Genuine OEM Part: — Supplied as an authentic Multiquip OEM component, this part meets the exact material and dimensional requirements of the original valve.
• Confirmed Fitment Across Generator Families: — Verified for use with MQP20P standby generators and SG-series studio generators including SG1400C3-55748, SG1400C4F, and SG1600C4F.

A locking ball valve controls the flow of fuel or fluid through a line by rotating a drilled ball within the valve body to open or close the passage. In generator applications, this type of valve is commonly positioned in the fuel supply circuit, allowing technicians to shut off flow safely during maintenance, filter changes, or extended storage. The locking feature adds an additional layer of control by preventing the valve handle from being turned unintentionally. When a ball valve fails — through seat wear, body cracking, or a stuck mechanism — it can result in fuel leaks, inability to shut off supply, or uncontrolled flow that creates both a fire hazard and a service liability. Replacing a worn valve promptly with a correct OEM part keeps the fuel circuit sealed and serviceable.
