Anti-animal and vegetable oil properNeoprene (CR) Butterfly Valve Seat
Neoprene (CR)
Neoprene, Polychloroprene is composed of chloroprene monomer polymerization. After vulcanization, it has good rubber elasticity and abrasion resistance. It is anti-insolation and has good weather resistance, resistant to violent distortion, refrigerants, dilute acid, silicon ester lubricant, but not resistant to phosphate series of hydraulic oil. It is easy to crystallize and harden at low temperature, weak storage stability, and big expansion in low aniline point of mineral oil. In using temperature range is - 50 ~ 150 degree.
Advantages:
Good elasticity and good compression deformation, the formula contains no sulfur, so it is very easy to operate. It has anti-animal and vegetable oil properties, will not be affected by neutral chemicals, fats, oils, a variety of oils, solvents, and also has anti-fire properties.
Disadvantages:
Do not recommend to use in strong acids, nitrohydrocarbons, esters, chloroform and ketone chemicals.
Application:
Rubber parts or sealing parts with R12 refrigerant, household appliances. Suitable for rubber products which direct contact with the atmosphere, sunlight, ozone parts, resist fire and chemical corrosion.
Certificate:
KTW W270 EN681-1,ACS,NSF61/372;WRAS,EC1935;FDA,EC1935;REACH,ROHS

At the heart of our product is the keystone EPDM PTFE butterfly valve liner, a component designed for excellence and efficiency. This liner combines the remarkable resilience of EPDM rubber with the unmatched chemical resistance of PTFE, creating a seal that is not only durable but also capable of operating smoothly across temperature ranges of -50 to 150 degrees Celsius. This dual-material approach ensures that the valve seat remains operational even under the harshest conditions, from freezing temperatures to the scorching heat, and in the face of a variety of chemical exposures. The practical applications of our butterfly valve seat are vast, suitable for media ranging from water, potable water, drinking water, to wastewater. This versatility makes it an ideal choice for municipal water treatment plants, HVAC systems, and industrial processes where the quality and reliability of fluid control are paramount. The black color of the liner is a testament to its robust nature, indicative of the strength and reliability embedded in its design. With our product, operators and engineers can trust in a solution that ensures the efficient and effective management of water and wastewater, maintaining system integrity and operational continuity.
