Balancing Valves

Balancing Valve is a double regulating, controlling and shut-off valve with a built-in pressure drop (in-line flow) measuring facility. Balancing problems are quite evident in multi-user systems, like Central Air Conditioning Plants and In-Process Heat Exchangers. The valve is a combination of a shut-off valve plus a Flow Regulating Valve and a Flow Measuring Station. It is not merely a valve but a system.

Advance make Balancing Valves provide a full complement (size ranges, pressure ratings, operating temperatures, and fluid characteristics) including related services such as on-site commissioning for optimum performance. Available in PN 16 / PN 20 or Higher (on request).

To suit the channel requirements, there are high temperature valves and low temperature valves capabilities in the same valve itself. In other words, these balancing valves can withstand extreme temperatures without spillage or breakdowns.

Salient Feature

  • Double Regulation :- This feature allows the valve to be used for isolation and to be reopened to its pre-set position to maintain the required flow rate and regulation. Ensures easy and reliable balancing of the system, regardless of any fluctuations in the differential pressure of the system.
  • Tamper Proof :- The valve can be set in pre-regulated flow conditions for Tamper-Proof positioning by a Built-in Locking Device.
  • Measurement of pressure Drop & Flow Rate :- common to Large Size Balancing Valve and Flanged Balancing Valve) The valves are delivered with two body taps and one set of pressure test quarter turn cocks. Pressure drop across the valve can be measured with ADVANCE make Portable Digital Differential Pressure Meter, having instant couplings with the pressure test cocks. Pressure test cocks are opened by 1/4th turn using a 7 mm square double end spanner. Flow through the valve can be calculated by turning the wheel, noting set hand wheel turns and measuring the differential pressure across the valve using the published Kv value for the valve for different hand wheel turns. Flow characteristics are available in the form of a Graph as well as in ADVANCE Flow Computation Software. The setting thus obtained can be locked by screwing in the lock screw and locking the lock nut which is protected by the lock shield on the hand wheel.
  • Application :- As a double regulating Balancing and Shut-off Valve in Hydronic systems. With special alloys, these valves can be used in Process plants too for double regulating & flow measurement functions.
  • Serice Suitability :- Liquid water, Steam and Ethylene Glycol.
  • Temperature Range :- From -40 deg C for low temperature valves to 120 deg C for high temperature valves standard; others available on request.
  • Maximum Flow :- The valves can handle maximum upto 5 m/s fluid velocity.
  • Flow Accuracy :- The valve performance is guaranteed within +7% of flow within the recommended operating range.
  • Direction of Flow :- The flow direction is marked by an arrow on the body.
  • Testing :- # Flow/Performance Test #Hydro Testing

The high-temperature butterfly valves are industrial valves designed to regulate or control the flow of high-temperature fluids or gases. These valves can withstand extreme temperatures of up to 1200°F (648°C), making them ideal for use in applications where high temperatures and pressure conditions exist.

The design of the high-temperature butterfly valves typically features materials that can withstand high temperatures, such as graphite, metal alloys, and ceramics. These materials allow the valves to operate effectively and safely under extreme conditions, minimizing the risk of damage or failure. These high temperature valves are essential components in industries such as power generation, petrochemicals, and refining.

Low temperature valves are crucial components in many industrial processes that involve extreme cold conditions. To ensure their reliable operation, a low-temperature test is performed on these valves. This test involves exposing the valve to temperatures below its rated minimum operating temperature and checking for any leakage or damage. The test helps to verify the valve's ability to withstand low temperatures without compromising its performance.

During the test, the valve is typically placed in a chamber where the temperature is gradually decreased to the desired level. The valve is then tested for any leaks or damage, and if it passes, it is certified for low-temperature operation.
