GLOBE VALVE DESIGN DISC STYLE TYPES
August 21st, 2023 by Amanda Schumann
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 […]
