Static valves control the flow of fluid through manual operation. They are commonly used in applications requiring isolation, regulation, or throttling, such as water treatment plants, HVAC systems, and industrial processes.
Unbalanced systems result in improper water distribution. Water will take the easiest path in the system where the resistance is lowest, resulting in excess water flow for the heating/cooling units closest to the pump.
Units far away from the pump will receive insufficient flow due to the unbalanced system. The flow rate is inconsistent, resulting in energy wastage and unbalanced temperature of the different units in the circuit❌
📈 The balancing valve is designed to balance the system, providing flow measurement and regulation👈
FIXED ORIFICE VALVE |
– Single integrated fixed orifice with one Kvs value
-More accurate measurement at any setting, even with debris
– Smaller tolerance on metering area, higher accuracy
– Higher pressure drop due to fixed integrated restriction
VARIABLE ORIFICE VALVE |
– Variable orifice with different Kv values for each setting
– Pressure drop specified by gap between seat and disc
– Changeable flow coefficient (Kv) and variable pressure drop
– Measuring accuracy ±5% when fully open, decreases as the valve closes
Micron rating is the smallest particle size in microns that the strainer can filter.
Define the filtration level, which is related to the filter’s opening area and the mesh hole size required for the application. If the hole sizes are too large, the filter will not be able to capture solid particles smaller than the hole sizes.
In contrast, too-fine filtration can rapidly increase pressure drop, damaging the plant components.
The disc and seat will be in direct contact with the flowing media.
| DISC ASSEMBLY
Discs without pins:
– Good corrosion resistance
Discs with integrated pin:
– Enhanced strength, withstands higher pressures
| SEAT ASSEMBLY
Vulcanized seat:
– Not replaceable
– Suitable for end-of-line services
– Most robust and most extended lifespan
Replaceable seats (thinner):
a. Backing ring:
– Easy to machine on the body
– Difficult to replace on-site
– Less expensive and less durable
b. Soft seat:
– Thicker construction
– Longer lifespan
– Easier to replace on-site
Gate valves are designed to either fully open or completely shut off fluid flow, making them ideal for isolation. Globe valves, on the other hand, are commonly used for throttling or regulating flow, offering better control over fluid movement and pressure.
Motorized butterfly valves use an electric actuator to control the opening and closing of the valve, providing automated flow control. They are suitable for applications requiring remote operation or automated system integration.
Expansion joints are used to absorb thermal expansion and contraction, reduce vibration, and accommodate pipe movement in various applications such as heating and cooling systems, pipelines, and industrial processes.
A suction diffuser is designed to provide a smooth flow transition into a pump, removing debris and reducing turbulence, thus increasing the pump’s efficiency and lifespan.
This depends on the type of butterfly valve.
Please download the Operation, Maintenance, and Installation manual (OMI) on the product page.
1 | Possible reason
Joints are used between the liner and the flange. The joints push the elastomer inwards, increasing the operation torque, which prevents the valve from opening and closing.
1 | Remedy
Remove the joints between the liner and the flange.
2 | Possible reason
The internal diameter of the flange has exceeded the correct measurement; The liner is not held firmly in place. The constant movement of the disc displaces the liner inwards into the valve and blocks the disc movement.
2 | Remedy
Replace the butterfly valve.
1 | Possible reason
The bolt(s) are not correctly tightened.
1 | Remedy
Tighten the bolts diagonally.
2 | Possible reason
Damage to the flange holes is due, e.g., to excessive tightening of bolts or unsuitable valve lifting.
2 | Remedy
Replace the valve.
3 | Possible reason
The bolt(s) are not uniform.
3 | Remedy
Use uniform bolts suitable for the flange holes.
4 | Possible reason
The seat/gasket is damaged.
4 | Remedy
Replace the seat/gasket.
5 | Possible reason
Lack of parallelism of the counter flanges.
5 | Remedy
Ensure uniform pressure on the seat on both faces.
1 | Possible reason
Incorrect fitting of test points.

A pressure rating is cast into the valve’s body. It indicates the maximum pressure that the valve shell is capable of supporting in normal operating conditions.
Nevertheless, the flange drillings could be PN10, PN 16, PN20, PN25, ANSI 125, ANSI 150, etc.
