Component Specifications

Definition
The Valve Body & Seat in solenoid valves serves as the main housing that contains the internal flow channels and provides the critical sealing interface between moving parts. The body forms the pressure boundary and flow path geometry, while the seat creates the sealing surface against the valve plug or disc to enable precise on/off or proportional control of liquids or gases in automated systems.
Working Principle
The valve body provides the structural framework and flow path, while the seat creates a precision sealing surface. When the solenoid is energized, the plunger moves to open or close the flow against the seat, creating a tight seal to prevent leakage. The body withstands system pressure and directs fluid through designed orifices.
Materials
Stainless steel (304, 316), brass, aluminum alloys, engineered plastics (PTFE, PEEK), with seats often made of elastomers (EPDM, Viton), PTFE, or metal alloys for specific media compatibility.

Frequently Asked Questions

What materials are best for corrosive fluid applications?

Stainless steel 316 bodies with PTFE or PEEK seats provide excellent corrosion resistance for most aggressive media.

How does seat design affect valve performance?

Seat geometry directly impacts sealing effectiveness, response time, and service life. Soft seats offer better sealing but lower temperature limits, while metal seats handle higher temperatures but may allow minimal leakage.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
