Ritag dual plate swing check valves

Description

RITAG Type ZRD / DIN and API dual plate check valve

Wafer type
Material: Stainless steel
Sizes DN50 – DN1400

The RITAG Type ZRD dual plate check valve is the most universal check valve among the nonreturn valves. It is available in a broad spectrum of nominal diameters and nominal pressures. Thanks to the dual-plates, which create the optimum dynamic flow behaviour, this valve design has proven to be an outstanding solution for most process requirements in plants and pipe systems. The dual plate check valve is perfectly suited for use with vapours, gases and liquids.The well thought through design requires no drilling in the housing (retainer-less design) and therefore has no housing seal other than the flange seal. Thus, testing for volatile emissions (fugitive emissions)is not required.

Suitable for all common flange standards and flange facings.
Four different designs for each flange standard are available:

Wafer
Flanged
Solid Lug
Tapped Lug
Many materials available for any request.

A large variety of elastomers and metal based solutions are used in the design of these functional seals thus offering a solution for nearly all media.
