DIAPHRAGM AUTOMATIC CONTROL VALVES SERIES 879

Control valves series 879 can help reduce water losses and contribute to efficient water supply management. With the help of the control pilots assembled on the hydraulic valve circuits, the hydraulic regulation valves ensure the monitoring of the pressure, the flow, the levels and the pumping stations, regardless of changes in the supply network.

AVK diaphragm operated control valves are designed to provide network stability, accurate regulation, easy maintenance and long durability.

AVK control valves are available in DN50-600, with reduced and with full bore. Control valves with reduced bore are appropriate for most applications, as the smaller bore often offers more accurate regulation. Control valves with full bore are recommended, if high Kv values are needed, e.g. in front of hydrants.

The body and bonnet are made of ductile iron with fusion bonded GSK approved epoxy coating. All non-coated internals are of stainless steel AISI 304.

The diaphragm is manufactured by AVK GUMMI and made of drinking water approved EPDM rubber with polyamide reinforcement.

Parabolic plug design provides precise regulation and stability at low flow. Furthermore, it reduces noise and vibration.

FUNCTIONS

Downstream pressure reducing valve

ACMO S879 M100 diaphragm operated control valve for pressure reducing applications (PRV) automatically reduces a higher inlet pressure to a lower outlet pressure. The outlet pressure is kept constant, regardless of changes in flow or
inlet pressure. The main control valve is pilot operated, capable of precise setting and easy adjustment of outlet pressure.

Upstream pressure sustaining valve

ACMO S879 M200 diaphragm operated control valve for pressure sustaining applications (PSV) automatically sustains a minimum pre-set inlet pressure, regardless of changes in flow rate or outlet pressure, to prevent of robbing
of pressure in upper zone. It is usually installed in a line between an upper zone and a lower area of heavy demand or tank. The main control valve is pilot operated, capable of precise setting and easy adjustment of inlet pressure.

Pressure relief valve

ACMO S879 M300 diaphragm operated control valve for pressure relief applications, automatically, discharges excess pressure above a pre-selected value, to prevent overpressure. The main control valve is pilot operated, capable of precise setting and easy adjustment of inlet pressure. It is usually installed on a pipe branching off from the main line.

Flow control valve

ACMO S879 M400 diaphragm operated control valve for flow control applications (FCV) automatically prevents excessive flow by limiting flow to a preselected maximum rate, regardless of changes in line pressure. The main control valve is pilot operated, capable of precise setting and easy adjustment of required flow. The valve is supplied with an orifice plate assembly; the pilot control responds to the differential pressure produced across the orifice plate installed downstream of the valve.

Altitude control valve

ACMO S879 M800 diaphragm operated control valve for level control applications with altitude pilot is an automatic control valve that controls reservoir filling and reservoir level without the need for floats or other devices. It is a non-modulating
one-way valve that remains fully open until the shut-off point is reached. The pilot control operates on the differential forces between a spring load and the water level in the reservoir.

Modulating float control valve

ACMO S879 M500A diaphragm control valve for level control applications with modulating horizontal float is an automatic control valve that maintains a relatively water level in a reservoir regardless of the varying demand. It can be installed to control the flow into or out of the reservoir. The float control pilot is remotely mounted into the reservoir, connected to the valve cover by the means of a control pipe. The float control moves when the water level changes; this action varies the pressure in the upper control chamber, causing the main valve to throttle and regulate the flow.

Modulating float control valve

ACMO S879 M500 diaphragm control valve for level control applications with modulating vertical float is an automatic control valve that maintains a constant water level in a reservoir regardless of the varying demand. It can be installed to control the flow into or out of the reservoir. The float control pilot is remotely mounted into the reservoir, connected to the valve cover by the means of a control pipe. The float control moves when the water level changes; this action varies the pressure in the upper control chamber, causing the main valve to throttle and regulate the flow.

Dual stage day/night and solenoid control

ACMO S879 M117 diaphragm operated control valve for pressure reducing applications (PRV) automatically reduces a higher inlet pressure to two lower outlet pressures according to the time of the day. The outlet pressures are kept constant, regardless of changes in flow or inlet pressure. The main control valve is operated by two pilots, capable of precise setting and easy adjustment of outlet pressure. The switch between pilots is managed by the controller (timer).
