Tilting Disc Check Valve Factories & Factory Solutions for Indonesia

Tilting disc check valves feature a pivot point placed at an offset ratio (1/3 to 2/3 disc radius) and an inclined seat angle (5° to 15°). This reduces the disc stroke distance by up to 60%, allowing the valve to close rapidly prior to flow reversal. In high-head pumping stations across Indonesia, this eliminates severe slamming, pipeline vibration, and Joukowsky water hammer surges that frequently damage standard swing check valves.

For geothermal steam condensate containing dissolved H₂S, CO₂, and silica scaling (such as in Kamojang or Lahendong), we recommend ASTM A216 WCB or A351 CF8M bodies paired with NACE MR0175 compliant Duplex 2205 or SS316 internals. Body and disc seating surfaces should be hardfaced with Stellite 6 to prevent high-velocity erosion-corrosion and wire-drawing wear.

Standard swing check valves allow slurry particles to settle around the top hinge pin, causing mechanical binding. Tilting disc check valves utilize an eccentric shaft that lifts the disc cleanly off the seat ring without dragging. The internal fluid dynamic passage washes continuously over the pivot area, preventing slurry build-up and ensuring reliable non-return operation in high-density hydrometallurgical processing lines.

Our factory manufactures tilting disc check valves across a complete range of international standards: ASME B16.34 / API 594 (Class 150 to Class 1500), DIN / EN 1092-1 (PN10 to PN100), and JIS B2220 (10K to 40K). Flange face options include Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ), and Butt-Weld (BW) ends.

Yes. For critical raw water mainlines or long-distance transmission conduits, we supply tilting disc valves integrated with external hydraulic oil cylinders (dashpots) and adjustable counterweights. This allows engineers to fine-tune a 2-stage controlled closure: 80% rapid closing to arrest reverse flow, followed by 20% slow dampening to cushion final seating.

To prevent disc flutter and seat hammering, fluid velocity should meet or exceed the minimum fully-open velocity ($V_{min} = C \cdot \sqrt{v_s}$, where $C$ is a constant depending on disc mass and $v_s$ is specific volume). Our technical sales engineering team provides full sizing and $C_v$ dynamic calculation sheets for every project inquiry prior to manufacturing.

Every shipment includes a full export documentation package: Commercial Invoice, Packing List, Bill of Lading, EN 10204 3.1 Material Test Certificates, Hydrostatic Test Inspection Certificates, and Form E (ASEAN-China Free Trade Area Preferential Tariff Certificate) to minimize import duty taxes at Indonesian customs ports.

We offer comprehensive OEM services including custom body cast logo casting, stainless steel nameplates, tag numbers, and heavy-duty protective coating systems (such as 300-micron epoxy coating for marine coastal environments like Cilegon or Balikpapan).
