S/B - Condensate collection / steam distribution
4.0 Description
4.1 Scope of applications
Condensate collection/steam distribution manifolds are used for the discharge/distribution/
collectioni of condensate, steam or hot water.
The information complies to the Pressure Equipment Directive 97/23/EC.
It is the responsibility of the machine planner to ensure compliance.
The special markings on the valve must be taken into account.
Refer to the catalogue sheet to see which materials are used in standard versions.
Please contact the supplier or the manufacturer if you have any questions.
4.2 Operating principles
(refer to Fig. 2 - Fig. 3 page 5)
The product concept is based on a robust modular design with integrated shut-off valves
(ball / seat chamfer). This modular design can be used as the basis for condensate
collection / steam distribution manifolds with between 2 and 18 secondary connections
(series … -02 to series …-18).
The valve is based on a hard-sealing (metal on metal) construction:
- body (Pos. 1) / screw fitting (Pos. 15)
- seat (Pos. 3) / body (Pos. 1)
- valve plug (Pos. 4) / seat (Pos. 3)
- safety back-sealing mechanism

B: spindle (Pos. 11) / spindle guide (Pos. 16)
There are also graphite rings (Pos. 5) which take over external sealing in the position
between “OPEN” or “SHUT”.
Valve position:
OPEN - Safety back-sealing mechanism effective when valve fully open.
SHUT - Valve plug (Pos. 4) / chamfer at seat (Pos 3) seal effective.
ATTENTION !
- Refer to the data sheet for applications, limits on use and possibilities.
- Certain media require or preclude the use of special materials.
- The valves are designed for standard operating conditions. If conditions exceed
these requirements, e.g. aggressive or abrasive media, the operator should
state the higher requirements when ordering.
- Valves made from grey cast iron are not authorised for use in systems subject
to TRD 110.
ATTENTION !
Do not use shut-off valves for OPEN-SHUT function to throttle volume flow.
