For a range of reasons, dependable and secure valves for processes involving toxic or corrosive chemicals and substances can be difficult to come by. Valves must, in all cases, be low-maintenance and able to perform reliably. Check valves for chemical applications, however, must also be able to withstand corrosive environments.
Corrosion-Resistant PTFE Valves
Polytetrafluoroethylene, or PTFE, is a useful material for manufacturing a corrosion-resistant chemical check valve. The non-stick, non-reactive PTFE formula tends to limit fluid adhesion and makes it an ideal application for hazardous and corrosive conditions. Industry scenarios can include the energy industry, food and beverages, aerospace and more.
A chemical check valve can come in a range of designs depending on the situation. In conjunction with other key components, the valve can help constitute complete systems for liquid transport. These systems can channel a variety of substances through a complex distribution system accurately and safely.
Depending on the cracking pressure and size of the requisite check valve, valve components may also consist of PVDF or Polypropylene. PTFE control springs are still suitable for 3 to 6 psi cracking pressures while springs that function in high cracking pressures are better constructed with doubled and precision-ground Teflon-coated stainless steel.
A well-established provider can manufacture high-spec, custom valves for leading companies encountering demanding design challenges. Decades of industry experience inform creative and innovative solutions, such as PTFE manual valves, solenoids, spray guns, air cylinders and other relevant products.
