Toilet flush valves – Concealed and exposed

 

W-103LC high pressure concealed duct toilet flush valve

The concealed 20mm toilet flush valves consist of three different types:

  • Walcro W-103CXP – Comes with a VR button use with standard back entry toilets.
  • Walcro W-103C – Comes with the XP button use with standard back entry toilets
  • Walcro W-103C-SS – Comes with a stainless steel sleeve for use in vandal prone locations. Use with prison toilets with extended inlet pipes.

Operating pressure range: 100 kPa – 600 kPa.

All three valves have the same inner design.  They are designed to be installed BEHIND the toilet wall in a space called a DUCT.  Access to the toilet flush valve is not inside the bathroom or where the toilet stands, but in the duct.  Many hospitals and some government buildings have ducts where all the water piping is installed.  It is also separate from the electrical and communications wiring.  All prisons have ducts and that is where the 103LC-SS is used. See the image below where the flush valve is placed.  The toilet can be either a wall hung or pedestal type, it does not matter, as long as it is a back entry model.  Top entry models require exposed flush pipes and are not suitable for vandal prone locations.

Installations:

  • Stainless steel toilet
  • HCL Pedestal pan
  • HDTX594 Shrouded stainless steel toilet
  • CMPX592 Wall hung stainless steel toilet

Features:

  • Made in South Africa
  • DZR brass
  • 100-600 kPa operating range

W-104C low pressure concealed duct toilet flush valve

Concealed toilet flush valve for low pressure. The 104LC range is a classic institutional flush valve since it incorporates a isolating valve.  The isolating valve is used when the valve itself must be maintained or repaired without cutting the water of from the whole floor/room or building. It basically makes maintenance work easy and is require in all institutional installations.

The isolating valve is attached between the flush valve and the wall. It is designed to make maintenance on the flush valve easier by not having to close the main water supply

The concealed 25mm flush valves consist of three different types.:

  • Walcro W-104LCXP – Comes with a VR button and isolating valve, use with standard back entry toilets.
  • Walcro W-10LC – Comes with the XP button and isolating valve, use with standard back entry toilets.
  • Walcro W-104LC-SS – Comes with a stainless steel sleeve for use in vandal prone locations. Also includes the isolating valve. Use with prison toilets with extended inlet pipes.

Operating pressure range: 30 kPa – 600 kPa.

All three valves have the same inner design.  They are designed to be installed BEHIND the toilet wall in a space called a DUCT.  Access to the toilet flush valve is not inside the bathroom or where the toilet stands, but in the duct.  Many hospitals and some government buildings have ducts where all the water piping is installed.  It is also separate from the electrical and communications wiring.  All prisons have ducts and that is where the 104LC-SS is used.

W-106C Low pressure concealed duct toilet flush valve

Concealed toilet flush valve for low pressure. The concealed flush valve model 106 is ideal for factories and mining or installations with slightly lower pressure than normal residential institutions. It does not come with an isolating valve so you need to install either a gate valve close by or make sure that there is a shutoff valve close by, otherwise you need to close the floor or buildings water supply to open the valve during maintenance times.

The concealed 25mm flush valves consist of three different types.:

  • Walcro W-106LCXP – Comes with a VR button and isolating valve, use with standard back entry toilets.
