The 5000 Series zone valve (V8043), designed for hydronic heating, is equipped with "soft close" technology, which reduces water hammer potential, the company says. The Quick Fit pushbutton actuator removal feature offers a robust metal-to-metal connection, states the manufacturer. Features include a patented ball seal design, rotating ball seal, triple O-rings, brass sector gear, and removable power head. According to the manufacturer, the contractor does not need to remove the valve from the pipe in order to change or replace parts inside.
