What is TA balancing valve?
BALANCING VALVES. BALANCING VALVE The STAD balancing valve delivers accurate hydronic performance in an impressive range of applications. Ideally suited for use on the secondary side in heating and cooling systems, and tap water systems.
What is a staf valve?
A flanged, cast iron (STAF) and ductile iron (STAF-SG) balancing valve that delivers accurate hydronic performance in an impressive range of applications. The STAF/STAF-SG is ideal for use mainly on the secondary side in heating and cooling systems.
Is a ball valve a balancing valve?
Balancing valves are ball valves or gate valves, but ball valves and gate valves are NOT balancing valves. Balancing valves are calibrated to allow certain flows through them with set points and scales built in to let all know what the valve is set for in the system.
What is a stad valve?
STAD Series variable-orifice threaded valves are designed for flow control and monitoring in climate control and domestic hot or cold water distribution systems. Balancing and control valve with threaded connections for heating, cooling and drinking water distribution systems.
Can you install balancing valves vertically?
The arrow must align with the direction of fluid flow. NIBCO balancing valves may be installed in either horizontal or vertical lines.
Can balancing valves be installed upside down?
1.2 CBV valves must be installed with flow in the direction of the arrow on the valve body. 1.3 CBV valves can be installed in horizontal or vertical piping. The metering ports should never be installed below the pipe (pointing down), as this will allow system sediment to accumulate in the ports.
How do you size a balancing valve?
Sizing balancing valves based on the minimum or maximum flow rates is not recommended. Valves should be sized using the nominal flow rate only. The Minimum Flow is calculated from the minimum open setting of the valve and a minimum pressure drop 1 Ft. WG (= 3 kPa).
How do I choose a balancing valve?
Balancing Valves should be selected according to GPM flows, not line sizes. Applies to liquids other than water. Correct the measured flow (q) by the density (γ) according to this formula. When the differential pressure and design flow are known, use this formula to calculate Cv value.
Where should a balancing valve be placed?
Shifting viewpoints on flow controls can cause disagreements where balancing valves should be located in closed loop systems. Many (including us at Hays Fluid Controls) agree that the balancing valves should be placed on the return side, whereas other companies may choose the supply side.
