Chemical Liquid Valve Non-Metallic Exterior, Air Operated, Insert Bushing Type Fitting Integrated, Space Saving

Chemical Liquid Valve Non-Metallic Exterior, Air Operated, Insert Bushing Type Fitting Integrated, Space Saving

SMC

SMC

A integrated/space-saving insert bushing type connector for chemicals, with non-metal exterior that prevents liquid pooling.
[Features]
· A non-metal construction that joins the actuator to the body without using any metal screws.
· Special structure allows the valve to open and close slowly, preventing the formation of micro-bubbles.
· Can be used with liquid chemicals such as acids, alkalis and ultrapure water.
· Prevents seat surface misalignment and internal leakage.
· Prevents heavy impact to the valve and the generation of particles.
· Prevents diaphragm deformation and damage due to back pressure.
