The flow through a globe valve follows a course that changes direction nearly 90º twice. But, because the seating of a globe valve is parallel to the line of flow of the liquid, the valve can be used to throttle the flow to any required degree or to give positive shut-offs. The economy and dependability of the Asahi/America globe valve make it desirable for many applications where this pressure drop is not critical. These valves are designed for manual operation only. |
Precise flow control Solid thermoplastic valve body provides excellent corrosion resistance PTFE bellows stem seal eliminates old style packing glands and minimizes maintenance Positive bubble-tight shut-off Plug and seat can be changed to accommodate a variety of valve coefficients (Cv) Plug (trim) can be characterized (linear or equal percentage) per requirements (see below) No metal to media contact Extremely corrosion resistant actuator constructed of glass-filled polyester (PEG) with stainless stell trim Maximum required air pressure is 90 psi 3-15 psi direct acting for sizes up to 1"
