Garlock Butterfly Valves: Trusted throughout chemical, petrochemical and many other industries Garlock Butterfly Valves For corrosive and abrasive media The economic advantages of reduced maintenance, smooth operation and exceptional service life are proven over and over again. Garlock valves set the standards in TA-Luft compliance. The reliability of Garlock butterfly valves is not only appreciated and well known at our customers but also certified with SIL 3 according to EN 61508. GAR-SEAL valves are used extensively where corrosive, abrasive and toxic media needs to be reliably...

The correct type of lining PTFE Void-free body liner and disc isostatic molded from virgin PTFE. High material density >2.16 g/cm3. Guaranteed lining thickness of at least 3 mm plus high crystallinity. FDA conform. Abrasive PTFE Is the chemical resistance of PTFE needed and the media also provided with abrasive characteristics, the use of PTFE anti-abrasive is recommended. This special PTFE compound is essentially resistant to mechanical wear with almost the same chemical resistance as virginal PTFE. Is the chemical resistance of PTFE media resistant temperature resistant abrasion resistant...

Garlock Butterfly Valves: Trusted throughout chemical, petrochemical and many other industries With reliability at the forefront Section through the head flange The shaft is sealed against atmospheric pollution and corrosion by two O-rings. TA-Luft compliant sealing is standard. If control connection is needed, it can be integrated to observe the shaft tightness. Body According to Pressure Equipment Directive the bodies of Garlock valves are approved by TÜV Rheinland according to DIN 3840 and EN 12516. Flange types The valves are available in Wafer, Lug and wafer tank truck type. Design The...

Garlock Butterfly Valves: Trusted throughout chemical, petrochemical and many other industries Materials Housing materials It is standard practice that the housings of the Garlock valves and fittings are manufactured from high-quality ductile cast iron (EN-JS 1049). Depending on the intended use, however, other materials, such as cast steel (1.0619) and stainless steel (1.4581) are also available. All housings are manufactured and inspected in accordance with the specification of the pressure equipment directive. Liner Depending on the intended use, a large selection of lining materials is...

Garlock Butterfly Valves: Trusted throughout chemical, petrochemical and many other industries Test engineering Testing All our valves are tested according to EN 12266-1 before they are sent out to you. Standard tests are body strength (P10), body tightness (P11) and seat tightness (P12). Also a functional test is performed. To ensure constant high quality valves all components are subjected to stringent testing running in parallel with all stages of production. Dimensions of liner thickness On all PTFE parts, the liner thickness is also checked in accordance with specific measuring...
