Replace costly, bulky flanged systems with compact wafer-style butterfly, gate, and check valves built for industrial piping. Ideal for procurement managers and technical directors who demand reliable isolation, flow control, and short lead times — without the markup.
✅ ISO 9001 · CE · RoHS · 10+ years export experience to USA, Saudi Arabia, South Africa & Italy
Many procurement managers and plant operators stick with traditional flanged connections out of habit — but the costs add up fast. Here are the most common pain points we hear from buyers like you:
The good news? A simple switch to wafer-style connections can eliminate most of these issues — and we have the engineering data to prove it.
Our wafer-type butterfly, gate, check, and globe valves are designed to bolt directly between two pipe flanges using a compact, lightweight body. This proven design eliminates unnecessary material, reduces installation time, and delivers bubble-tight shut-off. Here’s what makes our wafer connection valves stand out:
We control every step — from ductile iron casting to CNC machining and hydrostatic testing. No middlemen, no markup. You save 18–25% vs. European brands with the same ISO 9001 quality.
Every wafer valve undergoes 100% pressure testing (shell & seat), material certification, and dimensional inspection per API 609 / EN 593. Zero-leak guarantee on all resilient-seated models.
Need a special face-to-face dimension, lug-style drilling, or a custom liner material (EPDM, Viton, PTFE)? Our 10+ senior engineers deliver tailored wafer solutions in 7–15 days.
Standard wafer butterfly valves ship in 15–25 days (FOB Tianjin). Express production available for urgent orders — we’ve delivered a full 200-piece order to the USA in 18 days.
All valves meet ISO 9001, CE, RoHS, and REACH standards. Our ductile iron wafer check valves are fully compliant with Saudi Aramco and South African pressure vessel codes.
Wafer valves are 40–50% lighter than flanged equivalents. A 20ft container holds up to 1,200 wafer butterfly valves (vs. 600 flanged) — saving you up to $2,800 per shipment.
Our wafer-style lineup covers the most common industrial applications. All dimensions comply with ASME B16.34 / EN 558 Series 20.

Wafer butterfly valves are the standard for isolation and throttling in aeration lanes, filter banks, and pumping stations. Their compact design fits tight pipe galleries and reduces valve box costs.
API 609 wafer check valves prevent backflow in crude oil pipelines and refinery cooling water systems. Metal-seated versions handle high-temperature hydrocarbons up to 425°C.
Wafer gate valves provide positive isolation in condenser cooling, boiler feed, and ash handling systems. Lightweight construction reduces structural load on piping supports.
EPDM-seated wafer butterfly valves are ideal for chilled water loops — they close bubble-tight and require no maintenance for 50,000+ cycles. Proven in large district cooling plants in Saudi Arabia.
Case Study: A US chemical plant replaced 86 flanged gate valves with Thriveon wafer butterfly valves (DN100, Viton seat). Result: installation time cut by 55%, total savings of $47,000, and zero leakage after 18 months of operation. Full case report available on request.
We’ve compiled the most common questions from procurement and engineering teams to help you make an informed decision.
A wafer valve connection uses a slim body that fits between two pipe flanges and is secured by long bolts or studs that pass through the valve body and flange holes. Unlike flanged valves (which have integral flanges), wafer valves are lighter, more compact, and typically cost 20–30% less. They are ideal for butterfly, check, and gate valves in standard pressure applications.
Yes, but within limits. Our wafer butterfly valves are rated up to PN16 / Class 150 (16 bar at 120°C). For higher pressures (PN25 or Class 300), we recommend lug-style or flanged valves. For high-temp applications, metal-seated wafer check valves can withstand up to 425°C. Always consult our engineering team for your specific operating conditions.
Absolutely. We specialize in OEM/ODM customizations. Send us your existing valve sample or drawing, and our engineers will match the face-to-face, bolt circle, and keyway dimensions. Typical turnaround for a custom design is 5–7 working days.
Our standard MOQ is 10 pieces per size/type. For trial orders, we can offer a sample kit of 2–5 pieces at a reasonable price. We understand the need to test quality before bulk commitment.
Every valve undergoes a 3-stage QC process: (1) raw material inspection (spectrum analysis), (2) dimensional check during machining, and (3) 100% hydrostatic shell test + seat leakage test per API 598. We provide a Factory Test Certificate (FTC) with each shipment. Third-party inspection (SGS, BV, TÜV) is also available.
Standard lead time: 15–25 working days from order confirmation (FOB Tianjin). Express production (7–12 days) available for a small premium. For a 20ft container to the US West Coast, shipping cost typically ranges $1,800–$2,500 (subject to seasonality). We can help you arrange LCL or FCL.
We accept T/T (30% deposit + 70% balance before shipment), L/C at sight, and for established clients — net 30 days (subject to credit approval). We also accept PayPal for sample orders. All contracts are governed by ICC Incoterms 2020.

"We've been importing wafer butterfly valves from Thriveon for two years. Their quality consistency is better than any Chinese supplier we've tried — and we've tried five. The EPDM seats hold up perfectly in our chlorinated water system."
"Thriveon's engineering team helped us redesign a wafer check valve for our hydrogen plant. They changed the spring material to Inconel and added a PTFE seat — all within 12 days. Fast, competent, and professional."
"Cost was our main driver, but we were worried about quality. Thriveon provided free samples, third-party test reports, and even a video call during hydrostatic testing. We ordered 340 wafer gate valves — all passed inspection."
"The biggest advantage is the weight saving. Our project in Angola required air-freighting some valves — Thriveon's wafer connections saved us over $6,000 in freight alone. Plus, they arrived a week early."
"After a bad experience with another supplier, we switched to Thriveon for our wafer check valves. Their customer service is outstanding — they answer WhatsApp messages on weekends. Product quality? Zero failures in 18 months."
Take advantage of our Factory-Direct Pricing and 15–25 Day Lead Time. We'll help you select the right wafer connection valves for your application, with full QA documentation and after-sales technical support.
