Pneumatic & Electric Actuated PTFE Butterfly Valve

PTFE Butterfly Valve

ZECO Split Body PTFE Lined Butterfly Valve is manufactured in the size range of 40 mm to 400 mm, Body and Integral Disc with shaft material are available in Ductile Iron A395, Stainless Steel, and Carbon Steel duly lined with FEP, PFA.

PTFE Lined Butterfly Valve is available in Wafer Body Style in ANSI 150#, PN6, PN 10, PN16 Class operated by a Hand lever, Manual Gear, Pneumatic Actuator, and wide range of Accessories like positioner, proximity switch box, Limit switch, solenoid valve, etc

Our high performance PTFE lined butterfly valves are ideally suited for the stringent performance requirements demanded with isolating and controlling wet and dry chlorine gas as well as hydrochloric acid.

Anti Corrosive PTFE Butterfly Valve

ZECO electric fluorine lined butterfly valve is different from the conventional butterfly valve and valve plate lined with Teflon so that the media and valve body have isolation, antiseptic effect. The valve has more and more close closure functions and sealing.

This wafer type butterfly valve is for the chemical industry. Adopt PTFE as the seal and disc which has a powerful ability of anti-corrosion. Disc plate with frame structure, high strength, flow area, and flow resistance. The valve with more and more tightly sealed off function, a reliable sealing performance

Applicable to any concentration of acid, alkali salt and oxidative extrusion, reducing agent, organic solvents, and other media.

It could be equipped with an off-type actuator, modulating type actuator, and intelligent type actuator. Steam lined valve disc ensures lower pressure drop.

Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.

Applications of PTFE Butterfly Valve

PTFE butterfly valve is widely used in chemical, petroleum, metallurgy, medicine, and other industrial sectors to adjust or cut off the strong corrosive medium such as acid and alkali in the production process, and has the most obvious effect in the control of water treatment process. It is one of the most ideal choices for anticorrosive valve equipment at present.

PFA Lined Butterfly Valve Description

The body is epoxy coated ductile iron (non-wetted). They are available with Wafer style or Lug style 150# ANSI flange connections. They can be equipped with a manual lever or can be actuated with electric or pneumatic actuators. A full range of accessory items is available including limit switches, solenoid valves, positioners, and manual override devices.
