Product Description:
The sanitary pneumatic diaphragm valve is driven by pneumatic actuator and this type of valve is ideal for flow control as well as for open/close duties for various sanitary production lines. We produce three types of these pneumatic valves:
1. WLM-GPP002: Pneumatic diaphragm valve with plastic pneumatic cylinder
2. WLM-GPS002: Pneumatic diaphragm valve with stainless steel pneumatic cylinder
3. WLM-GPI002: Pneumatic diaphragm valve with intelligent actuator
