Pressure Reducing Valve Available At Pelmar Engineering Ltd.

The Bermad Model 720 Pressure Reducing Valve is a hydraulically-operated, diaphragm-actuated, pressure reducing control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure.

• Flow and leakage reduction

• Cavitation damage protection

• Throttling noise reduction

• Burst protection

• System maintenance savings

The Bermad Model 730 Pressure Reducing Valve is a hydraulically-operated, diaphragm-actuated, pressure reducing control valve that can fulfill either of two separate functions.

When installed in-line, it sustains minimum pre-set, upstream (back-) pressure regardless of fluctuating flow or varying downstream pressure.

When installed as a circulation valve, it relieves excessive line-pressure when above maximum pre-set.

• Prioritizing pressure zones

• Ensuring controlled pipeline fill-up

• Preventing pipeline emptyingPump overload & cavitation protection

• Safeguarding pump minimum flowExcessive line-pressure protection

Bermad 700 Series Hydraulic Diaphragm Pressure Reducing Valve for automatic control of water supply systems.

The Bermad 700 Series hydraulic pressure reducing control valves provide superior performance in the control and regulating of pressure, flow, water level pumping systems and additional applications in waterworks and industrial systems, as well as in supply networks for irrigation systems.

The Bermad 700 Series consists of valves for a wide range of applications and constitutes a product line of impressive completeness. Its unsurpassed reliability has been well proven over many years of use throughout the world.

The Bermad 700 Series is complemented by a comprehensive range of control pilot valves and other control accessories for total flexibility of application.

The Model 735-M Surge-Anticipating Pressure Reducing Control Valve is an off-line, hydraulically-operated, diaphragm-actuated valve. The valve, sensing line pressure, opens in response to the pressure drop associated with abrupt pump stoppage. The pre-opened valve dissipates the returning high pressure wave, eliminating the surge.

The Model 735-M smoothly closes drip-tight as quickly as the relief feature allows, while preventing closing surge.

The valve also relieves excessive system pressure.

• Eliminates surge for all pumping systems:

• Booster & deep well, single & variable speed

• Eliminates surge for all distribution networks:

• Municipal, hi-rise buildings, sewage, HVAC, irrigation

• Difficult to maintain, remote locations, older systems
