Water heater ball valves are compact and reliable shutoff valves designed to control the flow of water to and from a water heater system. They feature a quarter-turn operation for quick and easy isolation during maintenance or emergencies. Built to withstand high temperatures and pressure variations, water heater ball valves provide secure sealing and long service life. Their durable construction makes them suitable for both residential and commercial plumbing systems. Common applications include hot water supply lines, tankless water heaters, storage tank systems, and general plumbing installations where safe and efficient flow control is essential.
