One press tool can install all press fittings and valves with consistency you can't get with other methods. With fewer tools and fewer chances for mistakes, the technology ensures you can focus on delivering the best possible plumbing solution while meeting project deadlines with confidence.

MegaPress® and MegaPress®316 Globe Valves 

The new MegaPress globe valves are made from 316 stainless steel, feature adjustable PTFE stem seals, and are available in sizes ½” – 2”. Engineered to provide reliable, precise control, the MegaPress globe valves include a rising stem and multi-turn design, allowing for visual confirmation of the valve’s open or closed position with more precise modulation versus a quarter-turn valve. The adjustable PTFE packing nut means this valve not only provides excellent resistance to corrosion but also allows for easy maintenance and replacement, reducing downtime and labor costs.
