ASME Pneumatic Globe Valve
The ASME pneumatic globe valve adopts double‑acting cylinder. Remote valve control is realized by air intake from upper or lower chamber, featuring convenient and flexible operation. It has simple structure for easy manufacturing and maintenance, short stroke and fast opening‑closing speed. Cone‑surface sealing is applied between closure member and valve seat sealing face, delivering low closing force, erosion resistance and reliable sealing. The replaceable valve seat allows arbitrary material matching with closure sealing surface to satisfy working conditions and extend service life.
