Genebre 2402 – Dual Plate Wafer Check Valve PN25

The Genebre 2402 is a dual plate wafer check valve constructed from stainless steel 1.4408 / CF8M, designed for installation between flanges. The plates open via differential flow pressure and close by AISI 316 springs when flow decreases or reverses. No actuator is required.

Construction and Connection

Body and plates: 1.4408 / CF8M
Shaft and springs: AISI 316
Washers: PTFE
Seat: FKM / Viton, vulcanized into groove
Connection: EN 1092 PN25 and ANSI 150
EN 1092 PN10/16 up to DN200 only
Face-to-face: EN 558-1
Mounting: horizontal, vertical, or inclined, with flow direction as indicated on the body.

Operating Limits

Maximum working pressure is 25 bar. Temperature range: -20°C to +180°C. Sizes: DN50 to DN300. Minimum opening pressure: 40 mbar (DN50–DN65), up to 75 mbar (DN300).

Hydraulic Data

Kv values: 68 m³/h (DN50) to 2300 m³/h (DN300). Manufacturer’s pressure loss data is based on water at 20°C, horizontal flow. For other fluids, calculate based on density, flow, and allowable pressure drop.

Applications

Suitable for water, industrial liquids, HVAC, pump stations, and compatible chemicals where stainless steel body and FKM seat are required. Selection must consider temperature, FKM/PTFE chemical compatibility, and stable flow to avoid plate flutter.

Installation / Maintenance

Do not install immediately downstream of pumps, elbows, reducers, or other valves. Manufacturer recommends 10×DN upstream and 3×DN downstream. Seat is vulcanized and not replaceable separately; valve replacement is required if seat is worn.

Certificates

GENEBRE, S.A. has implemented a quality management system to control the designing and manufacturing of fluid control valves, as well as the distribution of home and public taps.

This system complies with the requirements of the current international UNE-EN-ISO 9001:2015, certified by the prestigious German certification organization TÜV Rheinland.

In 2000, GENEBRE began to comply with the European Business Excellence Model, more commonly known as the EFQM. As a result, in 2003, the Catalan Regional Government awarded us with the Quality Award. This new system enables us to ensure the quality of GENEBRE's products and also to offer added value to our clients.

In 2012, we obtained the certification for the Environmental Management System. This system is certified according to the UNE-EN-ISO 14001:2015, also by TÜV Rheinland. GENEBRE QUALITY AND ENVIRONMENTAL POLICY
