Spirax Sarco DCV10 & DCV10C Centrally Guided Disc Check Valves - Stainless Steel & Carbon Steel

Overview

The Spirax Sarco DCV10 (stainless steel) and DCV10C (carbon steel) are wafer pattern disc check valves engineered for reliable non-return flow control in industrial piping systems. These centrally guided disc check valves are designed to be sandwiched between flanges, making them ideal for pump discharge lines, process piping, steam and condensate systems, and hot water applications.

The centrally guided disc design provides superior reliability and extended service life compared to conventional swing or lift check valves. When fluid flows in the correct direction, system pressure opens the valve disc against the spring. When flow stops or reverses, the spring immediately closes the disc, preventing backflow and protecting upstream equipment such as pumps and heat exchangers.

Both models are designed in accordance with BS EN 14341:2006 and fully comply with Indian Boiler Regulations 1950. IBR certification is available upon request at the time of order placement. Shut-off performance conforms to EN 12266-1:2003 Rate F.

Key Features

  • Centrally guided disc ensures consistent alignment and improved longevity
  • Wafer pattern design fits between ASME B16.5 Class 150 and Class 300 flanges
  • Spring-assisted closure prevents reverse flow before backflow can develop
  • Wide size range from DN25 to DN250
  • High temperature capability up to 400°C
  • IBR certified for Indian boiler and steam applications
  • Low maintenance – non-maintainable design with no user-serviceable parts
  • Dual orientation – suitable for horizontal or vertical installation
