Features & Benefits

FEP, PFA & PTFE Butterfly Valves

FEP & PFA Butterfly Valve

The FEP and PFA lined Butterfly Valves followed all standard criteria according to the API. FEP Valves can bear up to 160°C operating temperature and PFA can sustain up to 200°C operating temperature

PTFE Lined Butterfly Valve

Centric Disc PTFE lined Butterfly Valves are available in a 2” to 12” inch size range. PTFE sleeve Butterfly Valves with Mirror Finish Disc are very useful for powder applications as well. PTFE coated sleeve brings all the properties of PTFE. Due to this, the PTFE lined Butterfly valves can sustain 180°C operating temperature and easily handle extremely corrosive media.

The PN 10 pressure rating of lined Butterfly Valve becomes ideal for high pressurized media like gases, High chemicals, and viscous materials and it can be increased to PN 16 but on request. All these valves are available in wafer sandwiches and also provided the lug type body on request by the valve manufacturers.

The manufacturers can be your solution partner for Lined Butterfly Valves. We also offer Teflon Lined Butterfly Valves as per the customer’s requirements. The Lined Butterfly Valves are mostly used to control acidic and corrosive applications and these are highly demanded in chemical consuming sectors. The main purpose of using thermoplastic in valve industries is, to reduce the cost, increase valve performance, and prevent corrosion of valve from corrosive and hazardous fluids with the help of unique thermoplastic properties.

    Features & Benefits

    Atmospheric Leakage

    The benefit is resistance to permeation leading to extension of product life and operator safety because of lack of atmospheric leakage.

    Strong Sealing System

    Live loaded stem sealing system. The benefit is atmospheric sealing integrity and no manual adjustment over the life of the valve.


    ISO 5211 Actuator Mounting Pad for standardized actuator mounting

    High Temperature

    PFA, FEP & PTFE Lined is the Best for High Working Temperature

    Low Torque

    Low torque. The benefit is smaller operators taking up less space, ease of operation, and cost savings with less expensive automation packages.


    Blow-out proof shaft design for additional operator safety
