What valve solutions does ALLSEN offer?

Comprehensive valve solutions engineered for every critical application — from high-pressure pipeline isolation to zero-leak buried installations. Six product families, one standard of excellence.

ALLSEN trunnion ball valve for high-pressure pipeline isolation

Trunnion Ball Valves

High-pressure pipeline isolation with DBB/DIB sealing. Available in NPS 2–56, Class 150–2500. Engineered for the most demanding upstream and midstream applications.

ALLSEN floating ball valve for process isolation

Floating Ball Valves

2-piece and 3-piece designs delivering bubble-tight shutoff for process isolation. Compact, reliable, and built for continuous service across chemical and petrochemical plants.

ALLSEN fully welded ball valve for buried pipeline applications

Fully Welded Ball Valves

Zero-leak body design purpose-built for buried and district energy applications. No external bolting means no maintenance access required — install and forget.

Triple Offset Butterfly Valves

Metal-seated and fire-safe capable, handling service temperatures up to 600°C. The go-to solution when you need tight shutoff in extreme thermal environments.

Gate & Globe Valves

API 600 and BS 1873 style with OS&Y design. Available in Class 150–2500 for isolation and throttling service across power generation and refinery applications.

Check Valves

Dual plate wafer and swing check designs for non-return service. Compact wafer designs reduce weight and installation space without compromising flow performance.

Common Questions About ALLSEN Valves

Everything procurement teams and engineers need to know before requesting a quote.

What size range do ALLSEN valves cover?
ALLSEN manufactures valves from DN 15 to DN 3000, covering everything from small-bore process connections to large-diameter pipeline isolation. Trunnion ball valves are available in NPS 2 through NPS 56, ensuring we can meet virtually any project specification.
What pressure ratings are available?
Our valves are available in pressure ratings up to ASME Class 2500. Gate, globe, and trunnion ball valves span Class 150 through Class 2500, making them suitable for both low-pressure utility service and high-pressure wellhead and pipeline applications.
Are ALLSEN valves suitable for sour gas service?
Yes. ALLSEN offers NACE MR0175 compliant material selections across our product range. These materials are specifically chosen to resist sulfide stress cracking in sour gas environments, meeting the requirements of upstream oil and gas operators worldwide.
What documentation is provided with each order?
Every ALLSEN valve shipment includes comprehensive documentation: Material Test Reports (MTRs), Inspection and Test Plans (ITP), and all relevant certificates. We provide full traceability from raw material through final testing to support your project quality requirements.
What information do I need to request a quote?
To provide an accurate quote, our engineering team needs five key details: valve size, pressure class, process media, operating temperature, and end connection type. Additional details such as material grade, actuation requirements, and applicable standards help us configure the optimal solution for your application.
