APV vs LOW-COST COMPETITOR QUALITY GATE/ GLOBE VALVE
So, how does APV gate/ globe valve quality compare against its low-cost competitors? APV specifies smoothness tolerances on the stem and the stuffing box that are superior to our competitors. Many manufacturers still produce under much older versions of the API standard regarding smoothness. Of course, even the API smoothness level is an absolute base…

GLOBE VALVE DESIGN DISC STYLE TYPES
OPERATION Australian Pipeline Valve globe valves are for services requiring frequent operation for on-off isolation service as well as throttling. Never attempt throttling at under 20% of stem travel. Closer throttling, can result in higher pressure drops which may cause excessive velocities or cavitation and could cause vibration or high noise levels resulting in damage…
