LUG BUTTERFLY VALVE PTFE LINED

Lug Butterfly Valve PTFE Lined Product Information

Lug butterfly valve PTFE lined is used widely in the chemical industry and food industry, which is mounted between two matching flanges of the piping. And our PTFE lined butterfly valve has special gland structure, which can be adjustable, in this case our PTFE line valve has better sealing performance. And it’s with direct mounting pad ISO 5211 standard, which make it be mounted with pneumatic actuator or electric actuator directly, no need mounting another bracket. Because this type of PTFE lined butterfly valve is with materials of steel and stainless steel, it can work with bigger pressure up to 25bar or even 300LB. According to actual piping conditions, wafer type butterfly valve can be manufactured according to different flanges standards, such as ASMEB16.5, JB78, JB79, JIS10K, EN1092. Wafer butterfly valve can be also mounted on the piping end as exhaust valve. We can manufacture the lug butterfly valve PTFE lined according to standard of GB/T12238, ASME B16.34 with sizes of 1-1/2”~20” (DN40~500mm). 

1. FEATURES 

• Simple and compact construction

• Small in size and light in weight

• Quick 90° on-off operation, low torque

• Good sealing capability, no leakage

• With direct mounting pad, can be mounted with actuator directly, no need mounting the bracket for actuator.

• The gland is adjustable, better sealing performance

• Can put the valve internal parts out for repair or maintenance by disassembling the gland, no need assembling the butterfly valve off from the pipe
