I00 Series - hYflow High Performance Valves

BERMAD Irrigation 100 Series - 100 Series hYflow High Performance Plastic Hydraulic Control Valves Features and Benefits ■ Durable industrial grade valve design and construction uses glass-filled Nylon material to meet rough service conditions. ■ Ultra-high flow capacity with minimal pressure loss. ■ Designed for service on a wide range of pressure and flow conditions, from dripping to maximum flow. Simple design with few parts guarantees easy in-line inspection and service. ■ ■ Positive guided valve plug provides accurate motion and smooth regulation. Avoids chattering and slamming closed....

BERMAD Irrigation Basic valve I00 Series - hYflow IR-100 hYflow The BERMAD IR-100 hYflow basic model diaphragm actuated, hydraulically operated valve is at the leading edge of control valve design. It combines simple and reliable construction with superior performance, while at the same time being virtually free of the typical limitations associated with standard control valves. BERMAD’s automatic water control valves are designed for vertical or horizontal installation and are available in sizes of 11/2”, 2”, 2”L, 21/2”, 3”, 3”L, 4” & 6” DN: 40, 50, 50L, 65, 80, 80L, 100 & 150. The IR-100...

I00 Series - hYflow On-Off Modes 3-Way Control Line pressure applied to the control chamber of the valve creates a hydraulic force that moves the valve to the closed position and provides drip tight sealing. Discharging pressure from the control chamber to the atmosphere causes the line pressure under the plug to open the valve. 2-Way Internal Control Line pressure enters the control chamber through the internal restriction. The closed solenoid causes pressure to accumulate in the control chamber, thereby shutting the valve. Opening the Solenoid releases more flow from the control chamber...

BERMAD Irrigation Principle of Operation Fully Open Position When upstream pressure drops, the pilot blocks the supply pressure port and opens the drain port, venting the control chamber to the atmosphere. This fully opens the valve, minimizing head loss. Modulating to Close The pilot switches upon pressure rise, blocking the drain port and opening the supply pressure port. This pressurizes the control chamber, forcing the valve to modulate closed. Locked Position When sensed pressure is equal to setting, the pilot blocks both the drain and the supply pressure ports. This locks the pressure...

BERMAD Irrigation Product Features The cover ring fastens valve cover to body, stiffening and strengthening the valve body, enabling simple maintenance. A cover ring key is available. The pilot adaptor allows us to connect the mini-pilot valve or the Galit hydraulic relay to the valve body. The cover’s strong construction meets rough service conditions. Optional cover types (3”; DN80 and smaller valves) are capable of accepting a Flow Stem, a Flow Stem + Position Indicator, and a 2-Way Solenoid (2W-N1 Electric Type). [4] Auxiliary Closing Spring One single high grade stainless steel spring...

BERMAD Irrigation Main Models 100 Series Basic Hydraulic Valve, Model 105-Z Model 105-Z, is a hydraulically self-operated, diaphragm-actuated valve, which uses the hydraulic force of the existing line pressure, or any external hydraulic command (water or air), to open and close. Recommended for all On\Off applications, Model 105-Z is particularly suitable for agricultural irrigation heads, and filter stations. Electric Valve, Model 110-2W-N Model 110-2W-N, is a hydraulically self-operated, diaphragm-actuated, solenoidcontrolled valve. The valve opens fully and closes drip-tight in response...
