INTERCHANGEABILITY: ISO 16028 – NFPA T3.20.15 (HTMA) – SIZE 3/8 h3. MAIN DATA:
Series Q flat face couplings are an innovative product which finds ideal application in medium corrosive enviromental conditions. The Q series is a special version of F serie where the carbon steel components are treated with QPQ. In situations where the traditional surface treatments do not allow an acceptable performance but stainless steel can not be adopted, series Q offers an excellent performance/price relation together with all the advantages linked to the flat face design. Typical applications are: insecticides, diathermic oils, air conditioning fluids, water etc.
- Material: carbon steel QPQ treated
- Internal valves in austenitic stainless steel
- Springs in AISI 302, balls in AISI 420
- Perfect sealing of plug and socket both when coupled and uncoupled
- Extremely low spillage during connection and disconnection.
- No inclusion of air or external media during connection and disconnection.
- The flat faces are easy to clean
- Sleeve with a safety device preventing from accidental disconnection.
- Increased resistance to abrasion and corrosion
- Size 3/8 (DN 9) interchangeable to HTMA design
Since series Q is mainly associated to special applications, the requested seal type must be specified when an order is placed (please see page 8, point 6TH).
