Certificates and approvals
Pressure Equipment Directive (PED)
2014/68/EU
Valves classed as pressure equipment are designed to this directive and made under notified body supervision. For the buyer, the valve can legally enter the EU market, and the declaration of conformity ships with it.
CE marking
2014/68/EU
CE is not a certificate but the manufacturer's declaration. On these valves it is applied under the PED, together with the notified body number. Small valves that fall under Article 4.3 of the PED carry no CE marking.
TSE certificate
TS EN 1074
A product certificate from the Turkish Standards Institution, showing that the valve meets the standard for water supply valves. Often required in Turkish municipal and public tenders.
