SOLID’s Plastic Valve Lineup

Valve TypeDefinition & FeaturesTypical Applications
PVC Butterfly ValveCompact structure, rapid open/close. Disc size can exceed pipe diameter constraints. Optional pneumatic or electric actuators enable remote automation.Municipal water delivery & drainage, reclaimed water systems, chemical corrosion lines, pool water treatment
Diaphragm ValveFlexible diaphragm creates a complete seal with no dead zones—easy to clean. Ideal for media containing solids or suspended particles.Wastewater treatment, pharmaceuticals, food & beverage, toxic/liquid transfer
Gate ValveWedge‑shaped gate provides minimal flow resistance and full‑bore passage, resulting in very low pressure drop. Double‑gate designs resist water hammer.Large‑diameter water networks, water supply engineering, seawater desalination, mine drainage
Globe (Globe/Stop) ValveFluid passes through a seat and stem arrangement, offering precise throttling control. Soft‑seated options provide excellent shut‑off.Precision chemical reactors, pipeline flow control, instrumentation, laboratory equipment
Ball Valve90° rotation of a spherical ball enables quick, simple shut‑off or opening. Compact and offers excellent sealing; “Antiblock” design resists sticking after long idle periods.Acid/alkali waste lines, seawater circulation, automated production lines, HVAC systems
Check ValveHarnesses forward flow pressure to open the disc, and automatically closes on reverse flow to prevent backflow. Simple, reliable, and low‑maintenance.Sewage lift stations, cooling water loops, pump discharge lines, chemical circulation

Which Valve Is Right for You?

  1. Media Characteristics

    • Highly corrosive or containing solids → Diaphragm Valve, PVC Butterfly Valve

    • High‑purity liquid requiring dead‑zone‑free cleaning → Diaphragm Valve

  2. Flow & Pressure Drop Requirements

    • Large bore, low pressure drop → Gate Valve, Butterfly Valve

    • Precise flow regulation → Globe/Stop Valve

  3. Operation Speed & Frequency

    • Frequent cycles, rapid switching → Ball Valve, Butterfly Valve

    • Infrequent use, large diameter → Gate Valve

  4. Automation Needs

    • Remote control or interlocking → Butterfly Valve or Ball Valve with pneumatic/electric actuator

  5. Installation & Maintenance Convenience

    • Limited space → Butterfly Valve (slim profile)

    • Minimal maintenance → Check Valve (self‑closing design)
