We have gained the trust of thousands of customers around the world who have trusted us because of our punctuality to timing and quality along with smart pricing and we have been in the market for the last four decades.

For meeting the growing use of variable speed pumps for HVAC applications, we have brought out a range of Differential Pressure Control Valves (DPCV) which is specifically aimed at optimizing system performance. Very much efficient, the DPCV is set to a maximum differential pressure that ensures flow cannot exceed a desired rate. It, therefore, helps reduce energy consumption, the risk of noise and simplifies the commissioning process. A differential pressure control valve ensures a constant differential pressure across a Hydronics system with variable flow. It is used in heating and cooling systems for climate control. The constant differential pressure guarantees an optimal function of the devices in the branch. A differential pressure controller comprises a valve and a pressure actuator. Differential pressure controllers in the primary system are mainly used to maintain a constant and lower differential pressure across a motorized control valve or total system/substation. The differential pressure controller should be used whenever the ratio between the maximum and minimum available differential pressure from the network is greater than 2. A differential pressure controller can also be used to perform flow limitation in combination with a motorized control valve. It is recommended to place the controller in the return after the components across which a constant pressure is maintained. In certain situations, mainly when the supply pressure is very high, it can be useful to install the differential pressure controller in the flow.

Primary Benefits –

  • Energy savings due to the removal of overflows in the pipes and homogeneous temperature returns.
  • Expendable systems without new commissioning: The DPCV valves are recommended for ensuring pressure independent zones. The benefit is to offer the possibility of easily creating new zones without updating the whole system.
  • The control valves always work at their best authority: When the control valves force the system to work at partial loads (TRVs), there is no impact on the differential pressure of the other zones.
  • Reduction of the noise in the installation by not exceeding the required differential pressure.

Features & Benefits

  • Quick and easy to install,
  • Long life expectancy and
  • Require little or no maintenance.
  • Available in sizes DN15 to DN50, they are PN16 rated and have an adjustable differential pressure range of 20 – 100kPa.
