The NIBCO MA0012H is a 1-piece miniature manual ball valve designed for 4-inch PVC piping systems operating under high-pressure conditions. Built from polyvinylchloride (PVC) with a natural color finish, this valve is rated for a maximum working pressure of 2000 psi, making it suitable for demanding water and fluid control applications. The tee-style handle provides a firm, positive grip for manual actuation, and the standard port configuration delivers reliable flow control in Schedule 40 pipe installations. Plumbers and pipe fitters rely on this valve type for isolation and shut-off duties in both residential and commercial plumbing systems.
The MA0012H is intended for use in 4-inch Schedule 40 PVC piping systems where a solvent-weld connection is required on both ends. The solvent x solvent end connection makes this valve a common choice for permanently bonded PVC installations in water treatment, irrigation, industrial fluid handling, and commercial plumbing applications. Its compact 1-piece body keeps the valve profile low-profile while maintaining structural integrity at working pressure.
Designed as an OEM-style replacement or new-installation ball valve for 4-inch Schedule 40 PVC piping systems using solvent-weld end connections.
Installation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing code requirements. Depressurize and drain the line fully before cutting into an existing system. Apply PVC solvent cement per the cement manufacturer's instructions, allowing full cure time before pressurizing. Do not exceed the rated maximum working pressure of the valve.
