Description
2" Aggressive Chemical Solenoid Valve PTFE, PVC or PP – 160A50
The 160A50 is a high-flow chemically resistant 2/2 way normally closed solenoid valve designed for controlling acids, alkalis, water and other aggressive industrial fluids.
Available with PVC, polypropylene (PP) or PTFE valve bodies, the 160A50 is the largest model in the Type 160 range and is designed for chemical processing, water treatment, dosing and corrosive fluid applications requiring high flow capacity.
The pressure-assisted diaphragm design incorporates a PTFE isolating bellows, creating a dry-armature arrangement that separates the solenoid mechanism from the process media. With a large 50mm orifice, 494.32 L/min water flow and a 0.3–6 Bar operating pressure range, the 160A50 provides substantial flow capacity for demanding chemical handling systems.
Valve Function & Operation
Function: 2/2 way normally closed
Operation: Pressure assisted / servo assisted
Valve Design: Diaphragm seat valve
Armature Design: PTFE bellows isolated dry armature
Normal Position: Closed when de-energised
Energised Position: Open
Minimum Differential Pressure: 0.3 Bar
Operating Pressure: 0.3 to 6 Bar
The PTFE isolating bellows prevents the process media from entering the solenoid armature chamber, providing additional protection when controlling aggressive and corrosive chemicals.
Ports & Connections
Nominal Size: DN50
PVC Body: 63mm cement socket
PP Body: 63mm weld socket
PTFE Body: 2" BSP threaded connection
The choice of PVC, PP or PTFE construction allows the valve body material and connection method to be selected according to the process media and associated chemical pipework.
Pressure & Flow
Operating Pressure: 0.3 to 6 Bar
Minimum Differential Pressure: 0.3 Bar
Orifice: 50mm
Water Flow: 494.32 L/min at 1 Bar pressure drop
Maximum Media Viscosity: 50 cSt
The large 50mm internal flow path makes the 160A50 particularly suitable for higher-volume chemical transfer and process applications where both flow capacity and chemical resistance are important.

Why Choose the 160A50?
The 160A50 is the largest valve in the Type 160 chemical-resistant range, combining a substantial 50mm orifice and 494.32 L/min water flow with PVC, polypropylene or PTFE body options.
Its PTFE bellows-isolated dry armature helps protect the solenoid mechanism from aggressive process media, while the 0.3–6 Bar operating range provides effective control for larger chemical processing and transfer systems.
For applications where corrosion resistance and high flow are both essential, the 160A50 provides a versatile alternative to conventional metallic solenoid valves.
