• Fuels, lubricating oil and flammable hydraulic oils, petroleum, air, gas, non-flammable hydraulic fluids, boiler feed water, condensate.
• Drinking water.
• Sea water.

EXECUTION

• Disc made of stainless steel AISI 316.
• Seal – rubber EPDM or NBR, (FPM/FKM on request).
• Other materials on request.

**OPTIONS**

• Manual drive
• Gearbox drive
• Electric or pneumatic drive.

Dimensions: DN 40 – 800
