Balancing Valves

Balancing Valve is a double regulating, control and shut-off valve with 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 Flow Regulating Valve and 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).

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 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 7 mm square double end spanner. Flow through the valve can be calculated by turning the wheel, noting set hand wheel turns and measuring 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 to 120 deg 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

Valves with pre-insulation from advance valves

Valve insulation all over the world is done ON-SITE

Valve Insulation is done on-site by stuffing insulation material between bolts and around the valve and flanges and then a valve box is made
With change in piping or maintenance, valve box is broken and remade
Each Valve takes 4 – 6 hours minimum to insulate.
It’s very hard to reach valve surface underneath bolts and shafts and insulate on site
Big challenge of availability of efficient and skilled labour who could do a good job of insulation.
Insufficient or improper insulation results in condensation
Air pockets inside the insulation causes unseen rusting
Loosely held insulation starts to deshape and break apart over time

Benefits of Valves with Pre-Insulation from Advance Valves

Valves are shipped from factory with insulation; High quality factory warrantied insulation on valves.
Insulation that hugs the valve body, Designed as per IS:12436(1988) & will have no condensation
Rapid installation and quick site turnaround, Proper insulation results in Energy Savings
Longer life of the valve as there are no air pockets
No commissioning issues and Each valve maintenance does not require rebuilding valve boxes. Valves can be removed with insulation intact and reinstalled without damage to insulation – time and cost saved
Low smoke emission and fire retardant PIR material is used for Insulation
PIR insulation allows insulation thickness to be reduced by 50% compared with cork, 44% compared with expanded polystyrene or fiberglass
