PPH Diaphragm Valve
The PPH Diaphragm Valve is a non-metallic, corrosion-resistant valve specifically engineered for regulating and isolating the flow of aggressive chemicals and abrasive fluids in industrial piping systems. Made from Polypropylene Homopolymer (PPH), this valve delivers excellent resistance to acids, alkalis, and solvents. It features a flexible diaphragm that isolates the flow media from the valve body and moving parts, providing contamination-free flow control with minimal maintenance.
Its compact and reliable design makes it ideal for use in demanding applications such as chemical processing, water treatment, electroplating, and mining industries. The PPH diaphragm valve is particularly effective for on/off and throttling services in systems handling corrosive or high-purity fluids.
Key Features of PPH Diaphragm Valve
Chemical-Resistant PPH Body – Provides high resistance to corrosive chemicals and solvents.
Isolated Flow Path – The diaphragm prevents contact between fluid and valve components for contamination-free operation.
Low Maintenance Design – Fewer moving parts reduce wear and maintenance needs.
Precise Flow Control – Suitable for both throttling and shut-off functions.
Flexible Diaphragm Options – Available in EPDM, FKM (Viton), or PTFE for chemical compatibility.
Visual Position Indicator – Indicates open/closed status for operational safety.
Manual or Actuated Operation – Can be equipped with electric or pneumatic actuators.
