Important Notes
Safety note
The control valve must only be installed by qualified staff.
“Qualified staff” are persons who are familiar with the procedures for installation and commissioning
of the product, and who have qualifications appropriate for their work, for example staff who have
received the following:
■ Training as specialists.
■ Training or instruction in the use of appropriate safety procedures in accordance with regulations
concerning safety standards.
■ Training or instruction in first aid and in accident prevention regulations.
The valve is under pressure during operation.
When loosening flanged connections, sealing plugs or stuffing boxes, hot water and/or
steam may escape.
Installation and maintenance work should only be carried out when the system is
depressurised: isolate the valve from both upstream and downstream pressure.
Make sure that the pressure in control lines is zero.
The valve is hot during operation.
This presents the danger of severe burns to hands and arms. Installation and
maintenance work should only be carried out when the system is cold.
Risk of severe burns and scalding over the entire body!
Before carrying out maintenance work on the valve or loosening flanged connections,
stuffing boxes or sealing plugs make sure that all connected lines are depressurised
(0 bar) and cooled down to room temperature (20 °C).
Danger of bruising: During operation moving internals can cause contusions to hands.
Do not touch the valve during operation! The control valves ZK 313 ASME are remote
controlled and can open and close very abruptly.
Sharp edges on internal parts present a danger of cuts to hands. Always wear industrial
gloves for installation and maintenance work.
Danger of eye injuries: Always wear safety goggles when mounting or checking the
equipment.
Danger
Usage for the intended purpose
ZK 313 ASME
The control valve ZK 313 ASME is intended solely for cutting off and/or regulating the flow of fluids
consisting of water, steam, or steam condensate.
Its use is permissible only within the allowable limits of pressure and temperature and only if the
chemical and corrosive influences on the pressure equipment are taken into account. Before
installation and operation, a check must be performed to ascertain that the valve is resistant to the
medium in the operational conditions that will exist.
To ensure safe operation of the valve ZK 313 ASME only actuators named and specified by GESTRA
may be installed on the control valve.
