Fire protection sprinkler system for bank

Providing a reliable fire extinguishing system for the Bank of Israel represented a host of challenges. BERMAD had to ensure the system is only activated during fire, to prevent fire damage from false alarms. See how BERMAD's fire protection systems provide reliable fire protection for the bank.

Pressure reducing valves for fire protection syste...

The thirty-kilometer-long Jerusalem railway in Israel comprises 20 kilometers of tunnels and 5 kilometers of bridges, descending from the hills to the coastal plain. This results in high water pressure in the supply lines, which must be reduced for safe use by firefighters. See how BERMAD's fire protection systems are designed to guarantee reliability in the case of fire.

Water supply for high-rise building Case Study

BERMAD was tasked with ensuring water supply for consumption and fire-extinguishing for a 60-story building year-round, 24/7 in Azrieli Town, Tel Aviv. BERMAD installed water pumps and control valves in the building. See this impressive water supply project

BERMAD Series 1000 – Approved for Drinking Water

BERMAD’s 1000 series represent a breakthrough in the supply of drinking water. The new lightweight composite PN16 (250 PSI) valve is corrosion free and will deliver years of trouble-free performance. This versatile control valve can be used for a variety of applications such as pressure reducing for municipal, level control for water reservoirs, flow control for water treatment plants and many more applications.

Pressure Reducing Station With Relief Valve –...

In this video, we show the commissioning and calibration of the BERMAD 720 pressure reducing valve and a BERMAD 73Q relief valve. Both valves are shown installed in a pressure reducing station equipped with pressure gauges, upstream and downstream isolation valves and an in-line strainer. This configuration is designed to reliably and accurately reduce a higher supply line pressure to a lower consumer line pressure regardless of fluctuating upstream pressure or flow rates. This station includes a pressure relief valve to relieve pressure spikes that might occur in the consumer supply line.

This video shows and instructs in the procedure for resetting or calibrating the BERMAD 720-2B pressure reducing valve with a low flow by-pass. The BERMAD 720-2B will reduce a high upstream pressure to a stable lower downstream pressure regardless of fluctuations in flow or upstream pressure, including static no-flow conditions. This valve is designed as a solution for pressure reduction where the variation in flow is extreme, as might be found in municipal water supplies. To achieve this the BERMAD 720-2B in effect uses two different sized valves in one unit, offering an ideal compact and cost effective solution. The BERMAD 720-2B therefore has two pilots, one controlling the main valve for normal or higher flows and the other a direct acting pilot dealing with off peak very low flows. This instruction includes the resetting of both pilots.

This video shows and instructs in the procedure for resetting or calibrating a BERMAD 42T or 42T-20 pressure reducing valve. The BERMAD 42T and 42T-20 will reduce a high upstream pressure to a stable lower downstream pressure regardless of fluctuations in flow or upstream pressure, including static no-flow conditions. This instruction includes the resetting of a BERMAD relief valve typically installed downstream of any pressure reducing valve, as any change in the pressure reducing valve set pressure, will require a corresponding resetting of the relevant relief valve. The BERMAD model 42T-20 in addition to acting as a pressure reducing valve includes a built in non-return or check valve characteristic making it particularly suitable for the check valve requirement in fire sprinkler systems. The 42T-20 also serves as a surge arresting valve at pump outlets, preventing damaging surge spikes at fire pump startup.

This video shows the commissioning and calibration of the BERMAD 720 pressure reducing control valve installed in-line with a BERMAD 794 shutoff valve. Both valves are shown installed in a pressure reducing station equipped with upstream and downstream isolation valves an in-line strainer and pressure gauges. This configuration is designed to reliably and accurately reduce a higher supply line pressure to a lower consumer line pressure regardless of fluctuating upstream pressure or flow rate. If consumer line pressure rises above a pre-set maximum the BERMAD 794 shutoff valve will close the consumer supply line. Thus the shutoff valve prevents the excessive pressure from entering the consumer pipeline until corrective action has been taken. Once closed, the shutoff valve will trigger a limit switch to alert the relevant authority to implement corrective action

This video shows the commissioning and calibration of the BERMAD BC-720 pressure reducing control valve installed in-line with a BERMAD 72S-H pressure reducing emergency backup or "watchdog" valve. Both valves are shown installed in a pressure reducing station equipped with upstream and downstream isolation valves, pressure gauges and an in-line strainer. This configuration is designed to reliably and accurately reduce a higher supply line pressure to a lower consumer line pressure regardless of fluctuating upstream pressure or flow rates. As a safety feature, the station includes a "watchdog" emergency backup valve, normally dormant and fully open and that will quickly enter into a pressure reduction mode if the consumer line pressure rises above a pre-set maximum value. As soon as the "watchdog" valve enters into operation a limit switch on the valve will be triggered to alert the relevant authority to implement corrective action.

This video shows the commissioning and calibration of the BERMAD 720 pressure reducing control valve installed in-line with a BERMAD 720-PD constant ratio pressure reducing valve. Both valves are shown installed in a pressure reducing station equipped with pressure gauges, upstream and downstream isolation valves and an in-line strainer. Use this configuration to enable the sharing of the load of a high differential pressure reduction between two valves. The primary pressure reduction of the station is achieved by a constant ratio Proportional Diaphragm valve. The secondary reduction by a pilot operated reducing valve to accurately reduce the pressure to the exact requirement. This dual reduction system offers higher reliability and safety, longer service intervals and a quieter operation
