• Avoiding hydraulic losses should be minimal therefore flow meters and damper servicing such systems will operate with low pressure loss as efficient operation and high accuracy will allow.
• However, in some cases where low flow velocities are a result of system design, it is equally important that enough differential pressure is available for accurate flow measurement. This requirement is achieved on the basis of a practical compromise between the need for precision and low hydraulic loss.
• Flow metering and damper allowing system design engineers to specify standard manufactured valves that will accommodate various system design options arising existing H&V Technology, weighing energy conservation reminders and standard legislation. Detailed description
• BS21 (ISO7) standard, ASME B1.20.1, for unit systems conforming to BS7350.
• Y-shaped globe valves have a characteristic disc directional bias towards equal percentage efficiency. Integrated entrance hole plate perpendicular to the fitted test point.
• Valve operation is by hand wheel.
• Flow measurement accuracy: ±5% (fully open)
