The Velan Y-Pattern Forged Bonnetless Globe Valve is designed for high temperature and pressure applications. These include high pressure drop, steam blow down, steam injection, and fast acting isolation.
The valve’s seat and stem are at a 65° incline for low flow resistance, which reduces pressure drop issues that can happen with vertical S-type globe valves. This design also reduces the accumulation of deposits and corrosion.
Its forged carbon steel one-piece body provides streamlined flow and easy disassembly for service. The non-spinning disc and seat are made from cobalt chrome alloy for tight shut-off and long valve life. The non-rotating stem reduces torque requirements and the potential for fugitive leaks.
