ER 40 Heating radiator vent valves VENT

   Application
Permanent and automatic venting.
   The ER 40 VENT valves can be used in all systems of water. The valve automatically vents hydraulic systems such as heating radiators, pipe manifolds, pipes, boilers, reservoirs and underfloor heating manifolds on a continuous basis. This automatic function improves operational safety (corrosion reduction) and enhances the user’s comfort (no airborne noises).
   The manual quick-venting allows the fast filling in of the system due to the venting capacity.

Advantages

Reliable, long-life operation

Versatile application in water-ducting systems

Additional manual quick-venting

Built-in automatic check valve requires no draining of the system in case of replacement of the valve insert

Small and compact design

Saving of energy by optimal vented system

   Operation
   The automatic operation of the vent valve relies on the special swelling discs built in the valve insert. In dry conditions, the swell discs allow air and gas to escape. The immediate swelling prevents water leakage.
   Manual air venting is achieved by undoing the knurled screw head and allowing air and gas to escape. Replacement of the valve insert (including seal and swelling discs) is possible due to the automatic check valve integrated in the vent valve.
   At the first start of operation, it’s possible that a few drops come out as long as the swelling discs are dry. This doesn’t occure in operation.

ES 42 Float air vents HY-VENT

   Application
Permanent and automatic venting.
   The valve automatically vents air from hydraulic systems such as heating, cooling, air conditioning and sanitary equipment on a continual basis.
   The combination of an air separator with the aerating and venting greatly increases the efficiency of the venting operation. The automatic self-sealing check valve prevents water from escaping should the vent valve need replacing.

Advantages

Automatic air venting of systems during filling or normal operation

Automatic venting at draining

Design allows dirt-sensitive operation

Trouble-free replacement of the float vent valve under full system pressure thanks to a check valve

Time saving installation of the float vent valve with the automatic check valve through self-sealing internal thread

   Operation
   A float-controlled valve opens as the volume of air increases and continually releases the air collected in the cap. The junction canal transports the water and air straight to the air cap.
   When combined with the upstream AIRSCOOP, this system ensures the efficient separation of the water-air mixture in the pipes immediately after the main degassing area in the heating system.

EL 43 Air separators AIRSCOOP

   Application
Permanent air separation for automatic venting.
   The air separator is fitted in the inlet pipe immediately behind the heating source. This is the point with the highest concentration of air and gas driven out of the water.
   The expansion occurring inside the AIRSCOOP and the built-in deflectors speed up the process of separating air and water.
   When combined with the float air vent (ES 42 HY-VENT), this system ensures air separation as well as elimination.

Advantages

High air separation capacity

Strong robust design

Service and maintenance-free structure

Connections for vent valve and safety valve or thermometer

   Operation
   The air expelled from the water into the heating circuit enters the air separator device as air bubbles. The flow-deflector in the housing drives the air bubbles to the top. The air is then vented outside via the vent valve.
   The air-separation capacity can be increased by installing a straight piece of piping of approx. 0.5 m in length upstream the separator.

UK 32 Multi purpose units TRI-BLOC

Application
Permanent and automatic venting, aerating as well as pressure relief.
The safety device is a multiple fitting for heating equipment in the performance range up to 50 kW (DIN 4751). The individual components are assembled into one unit and tested. A self-sealing manometer is included (not assembled). The unit also has a connection for an expansion vessel (R 3/4") or, if required, a filling valve (Rp 1/2").

Advantages

Four operations (venting, pressure relief, displaying, connecting) in a room-saving combination

Self-sealing component connections

Use of proven components (float air vent, safety valve, manometer)

Versatile positioning of the manometer (frontal, lateral)

Manometer with check valve

Float air vent with automatic check valve

   Operation
   Venting
A float-controlled valve opens as the volume of air increases and continually releases the air collected in the cap. The junction canal transports the water and air straight to the air cap.
   Pressure relief
The safety valve prevents the pressure from rising above the normal operating level by releasing heating water via a membrane.
