Lug Butterfly Valve

Key features/benefits

Lug butterfly valves with epoxy coated  ductile iron body are designed to control various media in commercial and industrial applications. Valve mount standard is DIN PN 16. Seat to flange seal, eliminates the need for flange gaskets. Disc is  precision machined 1.4408 (CF8M) . Two piece stem  and disc design enhances the flow capacity  and reduces turbulence.

Features

• ISO5211 top mounting for manual, air or electric actuators
• Unique wave line seat reduces torque and extends seal life
• Ductile iron body with 3-layer epoxy coating
• 316SS disc with 2-piece stem design enhances flow capacity
• EPDM, NBR (Buna-N), or FPM (Viton) seal options
• O-ring stem/shaft seals, same material as seat
• PTFE graphite reinforced stem bearings
• Pressure rated 230 PSI (16 Bar)
• Optional 10 positional locking hand lever

Applications

Lug body butterfly valves are used to control the flow of water, oils,  air, vacuum and other media compatible with the materials of construction. Valves can be operated with manual, air or electric actuators.

Four seal options are available :

EPDM , NBR (Buna-N), FPM, PTFE,  VMQ

Operation

Direct mount lug butterfly valves can be easily fitted with optional manual operator, air  actuator or electric actuator using the standard ISO5211 top mounting. Turning the  square stem one quarter turn rotates the  stainless steel disc and opens or closes the  valve. Unique wave line soft seat reduces the  torque required to close the valve and ex-  tends the seal life.

Temperature Range

EPDM: -20 to 120ºC , NBR(Buna-N): -15 to 85ºC , FKM: -15 to 180ºC , VMQ:-30 to 200ºC , PTFE:-20 to 200ºC

Options

• Hand lever with 10 position locking
• Gear Box
• Air Actuators
• Electric Actuators
