Electric Flanged Butterfly Valve PTFE Lined Product Information

Electric flanged butterfly valve PTFE lined is double flanged butterfly valve with PTFE lined mounted with electric actuator, which can be operated automatically by the control cabinet. 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 electric actuator directly, no need mounting another bracket.
