Single/double pipe manual valve
Adjustable for wall or floor connection
It can be installed either on the right or on the left side of the radiator
Built-in lockshield-valve
Interaxis 50 mm.
The manual valves 894 and 895 can be used on
systems with single and double pipe type radiators.
The valves can be installed only through the
lower radiator connection, which is used both as
fluid inlet and outlet.
In single-pipe systems, the radiators are connected in series, with respect to each manifold derivation. The 894 and
895 series valves, set for this type of system, send only a part of the flow to the radiator, while the remaining part of
fluid is bypassed and routed to the next radiator. In this way the radiators can be intercepted individually (for exclusion or maintenance), allowing the functioning of the radiators installed further downstream.
In the two-pipe system, the radiators are installed in parallel, with respect to all the manifold derivations. In this type
of system, the 894 and 895 series valves send up to 60% of the inlet flow to the radiator.
The valves series 894 and 895, in double pipe mode, incorporate in a single device the dual function of the manual
valve and of the lockshield that characterizes the systems where the fluid inlet valve is connected to the upper connection of the radiator and the holder to the lower one .
