PTX Rotary Joints - Rotary Joints for Steam Service
The PTX rotary joint and stationary syphon system incorporates the latest developments in seal design and drying technology for paper dryers. The lightweight design makes for easy installation; yet its heavy-duty construction handles high pressure, high speed, and angular misalignment. The PTX rotary joint can also accommodate thermal expansion of the dryer journal – even when used on the front side of paper machines.
The patented PTX steam joint design uses a spring-loaded piston that applies balanced pressure on the seal ring to keep it securely seated against the seal plate. With its spring-loaded piston and reverse seal, the PTX seal technology is a far different design than conventional seal packages. These advanced design differences make the PTX rotary joint a more reliable, easier-to-maintain joint - even under the most difficult operating conditions. The PTX rotary joint is rated up to 400° F (205° C), 160 psig (11 bar), and 500 RPM (8,000 fpm).
