CT5-1 – INSTALLATION AND OPERATING MANUAL
1. General Notes of Safety
1.1 Only use the valve for the intended purpose, in satisfactory condition, with respect for safety and
potential hazards.
1.2 Always observe the installation instructions.
1.3 Faults that may impair safety must be addressed immediately.
1.4 The valves are exclusively intended for the application area stated in these installation instructions. Any
other or further use is not valid as the intended use.
1.5 The manufacturer’s warranty for the setting of the valve shall be null and void if the sealed cover is
removed.
1.6 All assembly work is to be carried out by authorized specialist staff.
2. General Notes
2.1 Pressure limiting valves are high quality fittings which require careful handling.
2.2 The sealing surfaces are precision-machined at the seat and cone to attain the required seat tightness.
2.3 Always avoid the penetration of foreign particles into the valve during assembly and operation.
2.4 The tightness of a pressure limiting / overflow valve can be impaired when using hemp, Teflon tape, as
well as through welding beads, amongst other things.
2.5 If the valves are painted, make sure that the sliding parts do not come into contact with the paint.
3. Range of Application
3.1 As a Pressure Limiting Valve: for non-adhesive liquids, gas, steam for protection against excess pressure
in pressure tanks or steam boilers as well as pressure-holding equipment parts for pressure devices in
compliance with the EC pressure equipment directive.
3.2 As an Overflow Valve: for non-adhesive liquids gas and steam for pressure limitation and/or regulation,
for protection of pumps and as bypass valve. Overflow valves can also be used if there is counter
pressure.
4. Installation and Assembly
4.1 To ensure a satisfactory operation of the valves they must be assembled in such a way that the safety
valve is not exposed to any impermissible static, dynamic or thermal loads.
4.2 The installation has to be flushed before installing the valve. If an installation is not sufficiently cleaned
or the valve is installed improperly, the valve may leak even the first time it responds.
