| Process observation equipment to feature more robust gaskets |
L.J. Star standardizes on Garlock GYLON® gaskets for sight glasses, visual flow indicators
In an effort to continuously improve its products, L.J. Star, a leading manufacturer of process observation equipment, is implementing new standard gasket materials for all sight glass and visual flow indicator assemblies. The gasket materials, Garlock Sealing Technologies' GYLON 3504 and hygienic-type BIO-LOK™, allow for higher temperature capabilities, improved performance in chemical environments, faster delivery times on sight flow indicators and sight glasses, and easier installation and gasket replacement.
"It is always our intent to provide the best possible materials and as a result, we have made the decision to move from a PTFE envelope style gasket to Garlock GYLON 3504," said Jeff LaFleur, L.J. Star general manager. "We have been monitoring the performance of this gasket in the full range of process applications, industrial and hygienic; it has performed flawlessly."
GYLON 3504 is a proprietary modified PTFE material that is virtually impervious to the degradation caused by typical process chemicals. Gaskets made from this material eliminate the common need for retightening under working conditions. The GYLON 3504 material is capable of a temperature range of -450°F to +500°F, will not burn or support bacteria growth, and is FDA-compliant.
The GYLON BIO-LOK gasket, also made of a modified PTFE material, is designed for use in hygienic applications such as food, beverage,pharmaceutical and bio-processing. It can withstand the rigors of CIP/SIP processes. With no intrusion into the process flow, FDA and USP Class VI compliance, and exceptional chemical compatibility, the BIO-LOK gaskets are an ideal solution for nearly all challenging bio-process environments. They can withstand thermal cycling temperatures ranging from 41ºF (5ºC) to 356ºF (180ºC) without clamp retightening and pressures up to 800 PSIG.The non-elastomeric sanitary gaskets conform to key FDA regulations for materials (21CFR177-1550, 21CFR170.30, 21CFR175.300) and USP Class VI.In addition they meet the specifications of DIN 32676, ISO 2852, BS 4825,ASME-BPE, ISO 1127, and SMS.
