Toilet flush valves

Toilet flush valves are popular with institutional, commercial, industrial installations of wall hung toilets, back to wall toilets, free standing pedestal toilets, squat pans and slop hoppers such as those used in hospitals. There are various types, but can be categorized into two groups, either hidden or exposed. The hidden and exposed can either be manually operated via a push button or it can be Infra Red activated.

The WC-107C/LP is a 25 mm valve ideal for water inlet pressure range between 30 – 600 kPa. The 107 range should not be used in high security installations. Please use a duct system for prisons. High water pressure must be reduced with a pressure reducing valve. For optimum performance and low maintenance please install dirt strainers.

Walcro duct concealed toilet flush valves

In some cases vandalism is a problem so a completely hidden and out of reach flush valve must be installed. That is where a duct is used.  A duct is a long passage way behind the toilets where the flush valves are accessed and can be maintained.  So the flush valve is not accessible from within the bathroom. Three basic duct flush valve models are available and each has three different push button types or designs.

Handicap flush valves

Walcro 104 left and right hand handicap flush valve

The Walcro 104 can alternate for left or right hand use on site by simply rotating the isolating control valve inlet. The inlet is 25 mm diameter and operating pressure is between 30 – 600 kPa (± 3 – 6 Bar). If higher pressures are expected, especially during the night, install a pressure regulating valve.  Dirt strainers will also reduce maintenance and increase the life span of the valve, even if it is used with municipal water.
