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
  • Spare parts are available.

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.
  • Walcro W-106LC – Comes with the XP button and isolating valve, use with standard back entry toilets.

DAL Exposed Flush valve for toilets

The DAL exposed flush valve for toilets, slop hoppers and sluice sinks are affordable and reliable. These flush valves are exposed units and are ideal for top entry and back entry installations.

Normal operating pressure between 1.2 and 5.0 bar with a flow rate of 1.0 to 1.3 liters per second. The DAL flush valve range is extremely quiet so it is suitable for installations in hospitals, clinics and shopping malls. These units can even be installed in a home and schools. This is not a low pressure flush valve.

Technical Data

  • Flow pressure: min. 1.2 bar / recommended 2 – 5 bar
  • Operating pressure: max 10 bar
  • Test pressure: 16 bar
  • If static pressure exceeds 5 bar, a pressure reducing valve must be fitted before the flush valve.
  • Flow rate: 1.0-1.3 l/s
  • Temperature: Max 40°C
  • GR-37139000: Manual flow rate regulation
  • GR-37141000: Automatic flow rate regulation and comes with a vacuum breaker.

Walcro W-107 built-in boxed toilet flush valve

The Walcro W-07C/HP is a built-in boxed toilet flush valve with either 20 mm BSP inlet.  Designed for toilets in non-vandal areas.

After installation the flush valve is still accessible for maintenance.

Quite often used as replacement flush valve of older concealed urinal flush valves.

The built in boxed model is also often used when there is no duct behind the toilet for the W-104C, W-104CXP or W-104C-SS models. Ideal places where the built in flush valve is used are petrol stations, factories, mining (although duct type is better for these applications), shopping malls, schools and other non-vandal type of institutions. Note that the flush valve is accessible from the front (for convenience).

Pneumatic actuator for toilets and ducts

Pneumatic actuator for duct installed cisterns. The system is ideal for vandal prone installations where steel buttons, flanges and shafts get stolen. Since the whole system (excluding cisterns) are made from plastic there is no rust or material degradation problems which makes the pneumatic actuator ideally suited for coastal regions.

The low force with which the pneumatic actuator works also reduces wear and tear on the cistern mechanism prolonging the lifespan and reduced maintenance.

The pneumatic actuator can be used with stainless steel cisterns or plastic cisterns.  A special mechanism is required when used with stainless steel cisterns.

These actuators are ideal for duct installation with a low level or high level cistern.  The pressure pipe is 2000 mm long so the cistern can be fitted close to the ceiling.  With high level installations additional piping is required for connecting the plastic cistern to the toilet.

Features:

  • Ideal for duct installations
  • Used in industrial and commercial applications
  • Not recommended in high security or holding cell washrooms
  • Plastic design so it will not rust
  • Ideal for coastal regions
