Zubi T114AR – Flanged Disc Check Valve
The Zubi T114AR is a unidirectional check valve with a two-piece body and a centrally mounted, elastomer-lined disc. It is specified for applications where reverse flow must be prevented in water, chemical, slurry, or abrasive fluid networks, without the need for actuators or external control signals.
Technical Data
- Connection: Flanged.
- Flange standards: DIN PN10/PN16, ANSI 125/150.
- Pressure ratings by size:
- DN15–DN125: 10 bar
- DN150–DN250: 6 bar
- DN300–DN400: 4 bar
- Minimum opening pressure: 0.2 bar.
- Installation: Horizontal or vertical, depending on piping layout and flow direction.
Materials and Linings
Body materials: ASTM A216 WCB, GG25, GGG40, GGG50, CF8M / AISI 316, CF8 / AISI 304, or special alloys on request. Disc linings: Butyl, natural rubber, EPDM, Hypalon, Neoprene, Nitrile, or Viton. Body linings: Butyl, abrasion-resistant natural rubber, Ebonite, Hypalon, Halar / ECTFE, Neoprene, Rilsan.
Applications
Suitable for water, corrosive fluids, abrasive slurries, pulps, and chemicals, provided compatibility of lining, disc, and body is confirmed. For fluids containing solids, selection must consider flow velocity, risk of sedimentation, and required opening pressure.
Standards / Compliance
Complies with PED 2014/68/EU (Fluid Group 1(b), 2, Category I, Module A) and ATEX 2014/34/EU for Area 2 & 22.
FAQ
When is a lined body selected?
When the process medium is corrosive or abrasive and protection is required via lining instead of a full alloy body.
Is sizing required?
Yes. The minimum opening pressure of 0.2 bar must be compared to the available differential pressure in the installation.
