Learn more about easily converting from a double chamber to a single chamber valve. BERMAD's 700ES Double Chamber Actuator makes it simple.

The BERMAD Model IR-120-PD Proportional Pressure Reducing Valve is a double chambered, hydraulically operated, diaphragm actuated, Pilot-Less control valve that reduces higher upstream pressure to lower downstream pressure, at a fixed ratio. The double chambered valve operation is independent of valve differential pressure. This develops maximum power, ensuring immediate valve response combined with inherent non-slam closing

When we need to limit the flow using hydraulic methods (as opposed to electronic methods), the flow is not continuously measured & sampled (only during setting). Therefore, pilots are designed to hydraulically sense the differential of pressure or force/velocity associated with the varying flow. In most cases, downstream pressure varies due to the use of different irrigation methods, changing demand, unequal irrigation shifts, etc. In these cases, pilots must be designed to continually measure the differential pressure or force/velocity using an upstream Orifice Assy as a flow sensor and differential pressure pilot that continuously sense the actual flow in values of ΔP (connected by two sensing tubes). Pilots such as the Paddle Pilot (PC70) continuously sense the flow in values of ΔF (created by ΔV) on the paddle front versus the back sides. In special cases, the downstream pressure is constant, for example, in reservoir filling applications where the reservoir level is actually the downstream pressure. In these cases, the method of "PRV to Orifice" can be used because the constant downstream pressure (after the orifice) enables us to sense and control the Orifice upstream pressure by means of a standard pressure reducing pilot and a downstream orifice

In this video we’ll demonstrate how to add a solenoid or a BERMAD GreenApp controller to a 2-Way Top-Pilot valve.

BERMAD’s Series 100-IR-DC valves are the world's first to combine composite materials with a double chamber design. The result is a highly reliable, robust, and versatile solution that can handle virtually any irrigation challenge. BERMAD’s double chamber valve is often used in critical applications, where extremely quick response and fail-safe operation are crucial

In this short video, we are going to walk you through the process of installing a BERMAD Omega Controller, including mounting, connecting to a power source and setting up the controller in the BERMAD cloud.

To succeed in today’s challenging farming business, growers have to effectively manage precious resources such as water, nutrients and energy. Watch this video to learn about BERMAD’s Composite, precise, cost effective, light weight, easy to install & operate, buttery operated Electromagnetic Flow Meter – Suitable to all types of irrigation water. https://bermadize.bermad.com/irrigati...

In this short video, we are going to walk you through the contents of the BERMAD Omega Controller box, and show you the major components of our cloud-based irrigation control solution.

BERMAD Pressure Sustaining & Reducing Control Valve, IR-423, "How to Set" Demonstration

The Bermad 43Q Pressure Relief Valve is a hydraulically operated, diaphragm actuated control valve that relieves excessive line pressure when it rises above the preset maximum. Colin Kirkland demonstrates how to set the valve for optimum pipeline performance out on the field.

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.

In this video we’ll demonstrate how easy it is to calibrate and maintain BERMAD’s top-pilot valves, series 100 and 200, and to reconfigure them by adding a solenoid or controller. https://blog.bermad.com/irrigation/ho...
