Description
1½" Aggressive Chemical Solenoid Valve PTFE, PVC or PP – 160A40
The 160A40 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 160A40 can be configured to suit chemical processing, dosing, water treatment and corrosive fluid applications. The pressure-assisted diaphragm design incorporates a PTFE isolating bellows, creating a dry-armature arrangement that isolates the solenoid mechanism from the process media.
With a large 40mm orifice, 400.79 L/min water flow and a 0.3–6 Bar operating pressure range, the 160A40 provides excellent flow capacity for larger chemical processing and fluid transfer 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, making the 160A40 particularly suitable for aggressive and corrosive fluid applications.
Ports & Connections
Nominal Size: DN40
PVC Body: 50mm cement socket
PP Body: 50mm weld socket
PTFE Body: 1½" BSP threaded connection
The three body material options allow the valve construction and connection method to be matched to the chemical media and associated process pipework.
Pressure & Flow
Operating Pressure: 0.3 to 6 Bar
Minimum Differential Pressure: 0.3 Bar
Orifice: 40mm
Water Flow: 400.79 L/min at 1 Bar pressure drop
Maximum Media Viscosity: 50 cSt
The large 40mm internal flow path provides high flow capacity for chemical transfer, treatment and industrial process applications.
Construction & Materials
Body Options:
✓ PVC
✓ Polypropylene (PP)
✓ PTFE
Solenoid Tube: Stainless steel
Internal Parts: Stainless steel
Armature Isolation: PTFE bellows
Seal Options: EPDM or FKM
The PTFE bellows isolates the solenoid armature from the process media, leaving the selected valve body, diaphragm and seal materials as the principal media-contact materials.
Media Compatibility
Suitable for compatible:
✓ Acids
✓ Alkalis
✓ Water
✓ Chemical dosing fluids
✓ Aggressive chemicals
✓ Corrosive process liquids
✓ Compatible gases
Maximum Media Viscosity: 50 cSt
Chemical compatibility should be checked against the selected PVC, PP or PTFE body together with the EPDM or FKM seal configuration.
Coil & Electrical

Why Choose the 160A40?
The 160A40 combines a large 40mm flow path with chemically resistant PVC, polypropylene or PTFE body options and a PTFE bellows-isolated dry armature.
Its 0.3–6 Bar pressure range and 400.79 L/min water flow make it particularly suitable for larger chemical processing and transfer systems where both high flow capacity and resistance to aggressive media are required.
The choice of PVC, PP or PTFE construction provides additional flexibility when matching the valve to different acids, alkalis and process chemicals.
