Double Flanged Butterfly Valve PTFE Lined Product Information
Double flanged butterfly valve PTFE lined is high performance flanged butterfly valve with PTFE lined, which is widely used in the chemical industry and food industry. Our PTFE lined butterfly valve has special gland structure, which can be adjustable, in this case the 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.We can manufacture the double flanged butterfly valve PTFE lined according to standard of GB/T12238, ASME B16.34 with sizes of 1-1/2”~20” (DN40~500mm).
1. FEATURES
Double flanged ends
Quick 90° on-off operation
Bidirectional seal, 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
