The Schischek ExMax-15-F Actuator and Tork TKV904.25 Ball Valve Assembly represents a robust and reliable solution for industrial applications where precise and safe flow control of media is required. The combination of an electric actuator designed for explosive environments and a stainless steel ball valve with PTFE sealing ensures long life and a wide range of applications.

The ball valve Tork TKV904 is standardly supplied with L bore. If you require a version with T bore, please contact us.

The model TKV904.25 is made from stainless steel AISI 316 and fitted with PTFE seats, allowing its use with various liquids and gases. The assembly is therefore an ideal choice for demanding operations where resistance to pressure, temperature, and chemically aggressive media is required.

Suitable Media

• Liquids: water, steam, hydraulic and mineral oils, other neutral and chemically more demanding liquids within the resistance of PTFE.

• Gases: compressed air, nitrogen (N₂), carbon dioxide (CO₂), oxygen (O₂ – with clean assembly without grease), hydrogen (H₂ – limited), helium (He), argon (Ar), and other inert gases.

The range of use is from –40 °C to +180 °C and up to a pressure of PN 63 (63 bar).
