| Type | Description | Typical Application |
|---|---|---|
| Wafer Type | Compact body fitted between two flanges with bolts passing through both flanges | Standard isolation duty, water treatment, irrigation, cooling water lines |
| Lugged Type | Body with threaded inserts allows end-of-line service and tank isolation without disturbing downstream piping | Tank outlets, end-of-line service, high-pressure chemical lines, dead-end shutoff |
| Operation | Size Range | Use Case |
|---|---|---|
| Lever Handle | DN100 - DN200 | Manual operation with 7-position locking plate. Most cost-effective. |
| Gear Operator | DN250 - DN500 | Required for large diameters where lever torque is insufficient. Precise positioning. |
| Pneumatic Actuator | DN100 - DN500 | Automated control. Single-acting (fail-safe) or double-acting. With solenoid + limit switches. |
| Electric Actuator | DN100 - DN500 | For remote control applications. 24VDC, 220VAC, 380VAC options. |
| Seat | Best For | Temperature Range | Avoid In |
|---|---|---|---|
| EPDM (Standard) | Water, seawater, dilute acids/alkalis, hot/cold water | -15°C to +55°C | Oils, fuels, aromatic solvents |
| FPM (Viton) | Industrial chemicals, oils, hydrocarbons, fuels | -10°C to +55°C | Hot caustic, polar solvents |
| NBR (Optional) | Petroleum products, mineral oils, hydraulic fluids | -15°C to +50°C | Strong acids, ozone exposure |
UPVC butterfly valves with EPDM seats are the industry standard for seawater intake, brine reject, and RO (reverse osmosis) pre-treatment systems across the GCC region. Their corrosion resistance to chloride exposure outperforms ductile iron and rivals stainless steel — at a fraction of the cost. We've supplied DN200-DN400 valves to multiple desalination expansion projects in Saudi Arabia, UAE, and Oman, including pre-treatment manifolds and backwash systems.
Municipal and industrial water treatment facilities use UPVC butterfly valves throughout — chlorination dosing, sedimentation tank isolation, sand filter backwash, and chlorinated effluent discharge. UPVC's resistance to sodium hypochlorite (NaClO) up to 15% concentration makes it the standard choice over metal alternatives that corrode quickly in chlorinated environments.
Palm oil refineries operate large UPVC piping systems for CPO (crude palm oil) transfer, water washing, and effluent treatment. DN150-DN300 wafer butterfly valves are specified for tank isolation and pump suction/discharge service. Our valves have been delivered to refineries in Sumatra, Sarawak, and Sabah for 5+ years.
Chemical plants handling dilute acids (HCl ≤20%, H2SO4 ≤30%, HNO3 ≤30%), alkalis (NaOH ≤30%), and electroplating bath chemistry rely on UPVC butterfly valves for cost-effective corrosion-resistant isolation. With FPM seats, the valves handle a wider range of organic chemicals.
Large-scale irrigation projects across Saudi Arabia (Tabuk, Jouf), UAE (Al Ain agricultural zones), and Indonesia (sugar cane, palm oil plantations) use UPVC butterfly valves for main supply lines, sprinkler manifolds, and reservoir distribution. Mining operations use them for slurry handling, dewatering, and process water control.

For oils, fuels, or aromatic hydrocarbons, specify FPM (Viton) seat instead of EPDM. For higher temperatures or stronger acids, consider CPVC or PPH butterfly valves — also available from our stock.

For stock items (DN100-DN300 wafer type with EPDM seat, DIN PN10), shipping within 1-3 days from our Dubai or Jakarta warehouse. Local delivery: 2-5 days for GCC region, 3-7 days for SE Asia. For custom configurations (gear operator, pneumatic, FPM seat, JIS standard), 7-15 days production lead time plus shipping. Large project orders (200+ pieces) typically 20-30 days with full project documentation.
Our main GCC warehouse is in Dubai (Jebel Ali Free Zone). From Dubai, road freight to Saudi Arabia (Riyadh, Jeddah, Dammam) takes 2-3 days. For project orders 100+ pieces destined for Saudi Arabia, we can arrange direct shipment from China to Saudi port — typically Jeddah Islamic Port (sea freight 18-22 days). Email us your destination to coordinate optimal logistics.
Yes — our wafer body geometry fits between standard flanges of DIN PN10/PN16, ANSI Class 150, JIS 10K, and BS 4504 standards. The wafer fits between any two same-standard flanges. Send us a photo of your existing flange or specify the standard at order, and we'll ensure perfect fit. For lugged type, threaded inserts are matched to the specified bolt circle.
For applications with corrosive media (seawater, chlorinated water, chemicals), UPVC offers superior corrosion resistance at 30-50% lower cost compared to ductile iron with rubber coating, and 60-80% lower cost than stainless steel 316. UPVC also has lower weight (easier installation), no scaling/biofilm buildup, and longer service life in chloride environments. Limitations: working temperature capped at 55°C, lower pressure rating at large diameters, and not suitable for hydrocarbon fuels.
Wafer type sits between two flanges with bolts passing through both. Cheaper, lighter, more common — but cannot be used for end-of-line service (you must close both flanges). Lugged type has threaded inserts (or through-holes for lugs) that allow the valve to be bolted from one side only — useful for tank outlets, end-of-line shutoff, or when downstream piping must be disconnected for maintenance. Lugged costs about 25-40% more than wafer.
Yes — UPVC body with EPDM seat is the industry standard for seawater intake and chlorinated brine handling up to 15% sodium hypochlorite concentration. For desalination pre-treatment with FRP-typical chlorination levels (1-5 ppm), our valves have demonstrated 10+ years of service life. For higher chlorination duty (e.g., shock dosing 50+ ppm), we recommend FPM seat instead of EPDM.
Yes — we offer full automated assemblies with pneumatic (single-acting or double-acting) and electric actuators. Pneumatic options include 3/2 or 5/2 solenoid valves, inductive limit switch boxes, E/P positioners (4-20mA), filter regulators, and manual override units. Electric actuators in 24VDC, 220VAC, or 380VAC. We supply pre-mounted and tested actuator-valve assemblies ready for installation.
24 months against manufacturing defects from date of shipment. This covers body cracking, seat detachment, stem failure, and dimensional non-conformance. Excludes damage from over-pressure, chemical incompatibility outside our published compatibility data, or mechanical impact during installation. Failed valves are replaced or refunded after material return and analysis.
Yes. Sample policy depends on quantity: For project orders 100+ pieces, we provide free samples with freight collect (typically $80-150 international DHL/FedEx for a single DN100-DN150 valve). For smaller projects, samples are charged at our standard pricing and credited toward your first order. Sample delivery: 3-5 days globally via express courier.
Yes. We provide full OEM service including custom brand marking on valves and packaging, custom data sheets, custom packaging design, and NDA protection. Several of our distributors in GCC and SE Asia resell our valves under their own brand. Minimum for OEM: typically 200-500 pieces per SKU.
For project orders 100+ pieces or recurring distributor inquiries, ask about our preferred partner pricing and dedicated account management. We support distributors across Saudi Arabia, UAE, Qatar, Oman, Kuwait, Bahrain, Indonesia, Vietnam, Thailand, Malaysia, Singapore, and Philippines with localized service and inventory.
Free samples available for engineering evaluation (freight collect). MOQ from 1 piece for stock items. ISO 9001 certified manufacturer with 15+ years of plastic valve specialization.
