GGG50 Rising Stem Rubber Seat Gate Valve Description
The GGG50 Rising Stem Rubber Seat Gate Valve is a heavy-duty valve designed for reliable flow control in industrial fluid handling systems. With a rugged bronze body and bonnet, it can withstand high pressures and temperatures. The rubber seat provides tight shutoff and sealing when closed to prevent leakage and enable accurate flow regulation.
A key feature is the rising stem design. As the handwheel is turned, the stainless steel stem threads through the yoke bushing, enabling the gate to lift smoothly off the seat without binding. The stem is polished to minimize friction.
For easy installation, the GGG50 has NPT threaded ends to connect with pipes of the same size, in a range from 1/2 inch to 2 inches. It can be installed horizontally or vertically with hand tools.
The handwheel actuator allows convenient manual operation and visibility of valve position. Remote operation with electric or pneumatic actuators is also possible.
With pressure ratings up to 300 psi, the GGG50 is suitable for controlling water, oil, gas, steam and other media in industrial piping systems. Typical applications include flow regulation, isolation, sampling, pump control and more.
The GGG50 delivers reliable shutoff, corrosion resistance, low maintenance needs and long service life. Its robust construction ensures precise flow control and durability even under harsh conditions. For demanding industrial fluid control applications, the GGG50 is an excellent choice.
