Sanitary Hygienic 2-Way / 3-Way Pneumatic Diaphragm Valve

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

Product Description & Applications:
The sanitary hygienic pneumatic diaphragm valve is driven by pneumatic actuator. It is ideal for flow control as well as for open / close duties for various pharmaceutical, biotechnical, dairy, food production lines and equipment such as:
Fermentation tanks
Pharmacy dosing system
Cryogenic drying system
Aseptic filtration system
Purified water production system
Aseptic fluid transportation and CIP / SIP line, etc.

Working Principle:

  • a
    The pneumatic actuator drives the stem downwards.
    Close the valve
  • b
    The valve opens gradually.
    The medium starts to pass through the valve.
  • c
    The valve opens completely.
    The medium passes through the valve.

Optional Actuator Control Units:
We have several kinds of automation control units for you to choose from and they are listed below.
1. Electronic positioner,
2. Limit switch
3. Solenoid valve
4. Fast Feedback Switch

Name Input Signal Output signal Function
1 Electro pneumatic Positioner 4-20Ma;0-5V:1-10V Optional:4-20mA;0-5V;1-10V Remote flow control, temperature control
2 Limit Switch Built-in two passive contact switch Valve position switch position feedback
3 Solenoid valve AC220V:DC24V The solenoid valve power failure ,control air reversing, realize the pneumatic valve switch
4 Switch prompt feedback Built-in float switch Field operation observation(Standard configuration)

Features & Advantages:
Driven by strong and long lifetime plastic case pneumatic actuator
Operation mode can be spring return or double acting in NO or NC
Pneumatic driving mode to ensure efficient operation and more accurate flow control
Diaphragm structure protects valve from corrosion by separating medium and valve chamber
Connection ends can be tri clamp or butt weld
Highly hygienic grade materials, applicable for pharmaceutical, WFI, food and other chemical pipelines
