Frequently asked questions
What is the Kv value of a valve?
Kv is the flow of water in m³/h at 5–30 °C that passes through a valve with a pressure drop of 1 bar. It is the key figure for sizing control valves. The imperial equivalent, Cv, is expressed in US gallons per minute at 1 psi (Cv ≈ 1.156 × Kv).
What is the difference between PN and ANSI pressure classes?
PN (EN 1092-1) designates nominal pressure in bar at 20 °C, e.g. PN 40. ANSI/ASME classes (B16.5, B16.34) such as Class 150 or 600 are dimensionless ratings whose allowable pressure depends on material and temperature. They are not interchangeable — flange dimensions differ.
Do your valves comply with the Pressure Equipment Directive (PED)?
Yes. Our valves are designed and manufactured in accordance with PED 2014/68/EU and carry CE marking where required. Declarations of conformity and EN 10204 3.1 material certificates are supplied with every order.
How quickly can you deliver spare parts?
Standard trims, packings and gaskets for our current product lines are kept in stock and typically ship within 2–5 working days. For legacy or third-party valves, our engineers can reverse-engineer and manufacture replacement parts.
