BBS-10 Eccentric Check Valve
Brand: Burkert Fluid Control Systems
The sterile check valves are appropriate for fluids and steam sterilization. The design is so created that the flow direction is selectable, which improves the cost and simplicity of installation significantly. The new standards in the biotechnology and pharmaceutical industry are met.
These valves are suitable for horizontal applications, and still fully drain. The standard check valves have a opening pressure of psi: 2.90 (kPa: 20, bar: 0.2).
Features
- All medium contact materials traceable
- Suitable for CIP and SIP (cleaning in process)
- Flow direction selectable
- Self draining in horizontal installations
