Series G120 Globe & Angle Valves
Brand: Koso Hammel DahlThe thread retained seat ring of the G120 eliminates concern over thermal expansion issues and the need for elastomeric gaskets.
This design utilizes a single metallic gasket at the body to bonnet interface.
This all metallic construction makes this design desirable for many chemical applications.
The geometry of the trim components simplifies manufacturing when high alloy materials are required.
The contoured plug of the G120 is available with 3 standard trim sizes (full, 60% and 40%) and up to 7 reductions in some sizes.
The 1/2" - 1" valves are also available with spline trims for precise control of extreme low flow applications.
A variety of extension and bellows seal bonnet options further enhance this product’s capability in chemical applications.
Features- All metal construction (no elastomeric gaskets)
- Ideal design for applications that require high alloy trims
- Bellows seal bonnets are available for difficult or hazardous chemical applications
- Ultra-low temperature extension bonnets are available for services down to –320°F (–196°C)
