ISOLATOR PTFE LINED BUTTERFLY VALVE
Sizes 2 to 12 inch, 150 psi
stainless steel springs in both upper and lower stem journals ensure a constant
pre-energizing of the seals, which allows compensation for packing wear and thermal
contraction and expansion.
Upper and lower stem seals utilize multiple designs
and materials to supply the ultimate in sealing, safety and reduced downtime.
The thickest PTFE liner available in the industry provides a minimum thickness
of 1/8-inch for greatest protection against corrosive attack and permeation, resulting in
longer service life.
Virgin PTFE lining on all internal wetted surfaces is inert to both acids and
caustics, eliminating the need for costly, exotic metals.
|| Thin disc design provides high Cv with
Steel-backed RTFE bushings maintain stern alignment
through the seals, delivering longer valve and seal life.
Choice of silicone or fluoroelastomer (FKM) seat backing, depending on
application, increases valve performance.
Thermally applied polyester powder coating on valve body provides superior
impact and abrasion resistance, as well as resistance to most acids, preventing exterior
Direct actuator mounting eliminates brackets or coupling, reducing dead- band,
increasing ease-of-assembly and lowering installation costs.
Applications Ideal for the
most demanding industries, including chemical, semiconductor and pulp and paper. Typical
services include: nitric acid, sulfuric acid, hydrochloric acid, hydrofluoric acid, wet
chlorine, brine, chlorine dioxide, and ultra pure water. Special cleaning available for
valves used in chlorine and ultrapure water.
