BT-Maric constant flow valve type Wafers

Do you face any of the following challenges?

• Do you need a constant flow in applications with high flow rates—up to DN300—regardless of pressure variations?
• Are you looking for a compact and cost-effective constant flow valve for your piping system?
• Do you want to optimize water usage in your existing pipe network?
• Is water conservation a top priority for you?
   

BT-Maric Wafer-type Constant flow valves help you:

• to achieve a mechanical, cost-effective, and compact solution for maintaining constant flow at high flow rates—regardless of pressure variations
• to integrate easily into existing systems where space is limited
• to ensure long-term reliability with a maintenance-free lifespan of up to 20 years
• to deliver a consistent flow rate across multiple usage points
• to prevent tampering by locking in the specified flow rate—avoiding both accidental and intentional changes
• to protect downstream equipment by ensuring the exact flow rate at all times
• to reduce water consumption and promote sustainable use

This is how it works

BT-Maric constant flow valves utilize a flexible rubber control O-ring with an orifice diameter that responds instantly to fluctuations in water pressure.

As pressure differential increases, the orifice diameter reduces to maintain the pre-set flow rate.

Likewise, as pressure reduces, the orifice opens up to maintain the pre-set flow rate.

LOW PRESSURE

The ring has a larger opening at low pressure.

HIGH PRESSURE

At high pressure the ring is pressed against the conical body. The ring’s opening reduces and the flow remains constant.
