    • Basic Valve Vertical – 6BAS

    • Description The FRASER valve is a Hydraulic Actuated Control Valve. The Globe pattern design provides reliable control and consists out of four major components namely: body, bonnet, seat and diaphragm-stem assembly. The compact design allows easy access for maintenance without removing the valve from the line. The only moving part in the valve is the diaphragm-stem assembly. This assembly with…

    • Pressure Reducing Vertical – 6RPF

    • Description The Pressure Reducing function will maintain the downstream pressure constant under varying supply pressure and demand. The pilot senses the downstream pressure and regulates the Main Control Valve accordingly. A reduction in demand or increase in supply pressure will increase the pressure into the system. The pilot senses the changes in the system pressure and closes the Main Control…

    • Pressure Sustaining Vertical -6SPF

    • Description The Pressure Sustaining function positions the valve to maintain a minimum supply (upstream) pressure into the Main Control Valve. The pilot senses the supply pressure and opens on the supply pressure and opens the main valve until it reaches the pilot setting. The Main Control Valve then opens and supply demand into the system. Should the supply pressure reduce…

    • Level Control Vertical – 6FMF

    • Description The Level Control function maintains a constant level within a reservoir. The Main Control Valve is controlled by a float pilot situated in a reservoir. There are two types of float pilot valves; On/Off (maintains a constant level difference of up to 1m adjustable). Modulating (maintains a high level in a reservoir). On reaching a low level, the pilot…

    • Electric Solenoid Vertical – 6ESF

    • Description The Solenoid Control function either opens or closes the Main Control Valve, by means of an electrical solenoid. The Main Control Valve can be open or closed by energising or de-energising a solenoid valve. Water pressure is either pressurising or draining the chamber of the Main Control Valve. The Solenoid Control functions will either fully open or close drip…

    • Altitude Control Vertical – 6ALT

    • Description The Altitude Control function controls the water level in a reservoir from 6m up to an altitude of 45m above the Main Control Valve. The Main Control Valve is controlled by an altitude pilot that senses the change in head of the water through a sensing line. The pilot valve controls an accelerator valve, which in return controls the…

    • Pump Control Vertical – 6PCV

    • Description The Pump Control function eliminates pressure surges during starting and stopping of pumps. The Main Control Valve is in the closed position when the pump starts and will open gradually, slowly increasing the line pressure to maximum pumping head. A limit switch connected to the valve position indicator will give an open signal. While stopping the pump, a signal…
