Valve body: AISI 316L.

Valve seat: EPDM+PTFE

Max. working pressure: 

• Normally closed EPDM 87psi (6bar), PTFE 65psi (4.5bar) as default, Normally closed EPDM 116psi (8bar), PTFE 87psi (6bar) as option
• Normally open and double action EPDM EPDM 116psi (8bar), PTFE 87psi (6bar) 

Actuator can with plastic material or pure stainless steel material, NC/NO/AA type for choose from

Air supply port: M6

Working temperature range: -22 ~ 266°F (-30 ~ 130°C) or higher upon request

Inside treatment: Ra 16-32μin (0.4-0.8μm), Ra 25 (0.5μm) is the default.

 

Options

End connection can be butt-welded, sanitary tri-clamp.

Diaphragm can be pure EPDM or EPDM+PTFE

Inside surface treatment can be Ra 16μin (0.4μm).

The mini diaphragm valves can be with plastic pneumatic actuators or pure stainless steel actuators as below photos show, actuators can be NC/NO/AA operated for choose from
