Oil and Gas Pipeline Valve Solutions — Built for Every PSI, Every Mile
Backed by 40 years of high- and medium-pressure valve engineering since 1985, PANS delivers oil and gas pipeline valve solutions that cover the full energy value chain — from wellhead to terminal.
Engineered for Every Stage of the Pipeline
Upstream: Wellhead & Gathering
Upstream operations demand valves that hold tight under extreme wellhead pressures and aggressive produced fluids — including sour gas with high H₂S concentrations. PANS upstream pipeline valves are engineered from forged and high-grade alloy materials to resist sulfide stress cracking and ensure zero fugitive emissions from the first day of service.
Midstream: Long-Distance Transmission
Long-distance midstream flow control requires valves that combine piggability, bi-directional sealing, and automated emergency shutdown capability. PANS API 6D Trunnion Mounted Ball Valves — available up to 48" (DN1200) and Class 2500 — are the backbone of high-volume gas and crude oil trunk lines worldwide.
Downstream: Refining & Distribution
Downstream refinery valves must maintain precise flow control and zero leakage across processing units, storage terminals, and distribution manifolds. PANS Sleeve and Lubricated Plug Valves, combined with Bellow Sealed Globe Valves, deliver the leak-free performance required by modern ESG and emission compliance standards.
Pipeline Valve Products That Perform Under Pressure
Trunnion Mounted Ball Valve
The gold standard for API 6D ball valves in mainline pipeline service. Trunnion-supported design distributes seat load independently of line pressure, ensuring low operating torque and reliable bi-directional sealing.
- Size Range: 2" – 48" (DN50 – DN1200)
- Pressure Class: ANSI Class 150 – 2500
- Body Material: WCB, CF8, CF8M, LCB
- Standards: API 6D, API 6FA, Fire Safe, NACE MR0175
Fully Welded Ball Valve
Designed for buried pipeline and long-distance natural gas transmission. Welded body construction eliminates potential external leakage points, delivering lifetime sealing integrity without periodic bolted joint re-torquing.
- Size Range: 2" – 48"
- Pressure Class: Class 150 – 1500
- Application: Natural gas trunk lines, underground burial
- Standards: API 6D, ISO 14313
Double Block and Bleed (DBB) Plug Valve
A PANS flagship product for pipeline safety and maintenance isolation. Double block and bleed valve design provides two independent sealing surfaces with a bleed port between, enabling safe cavity venting without full line shutdown.
- Size Range: 2" – 24"
- Pressure Class: Class 150 – 900
- Application: Meter stations, manifolds, pigging systems
- Feature: Low opening torque via eccentric design
Inverted Pressure Balance Lubricated Plug Valve
PANS' proprietary Model ZDAX47 uses an inverted pressure structure that channels line pressure to assist sealing — dramatically reducing operating torque while maintaining bubble-tight shutoff at high differential pressure.
- Size Range: 2" – 24"
- Pressure Class: Class 150 – 600
- Application: Gas gathering, compressor station bypass
- Lubrication: Self-contained, field-reinjectable
Wedge Gate Valve / Flat Gate Valve
A reliable isolation solution for full bore gate valve applications where bi-directional sealing and piggable bore are required. Elastic wedge design compensates for thermal deformation, maintaining seat integrity across wide temperature cycles.
- Size Range: 2" – 60"
- Pressure Class: ANSI Class 150 – 900
- Body Material: WCB, CF8M, LCB
- Standards: API 600, API 602, BS 1414
Cast Swing Check Valve
Engineered to prevent costly backflow damage to pumps, compressors, and turbines in oil and gas service. Internal pin-hinge design eliminates external packing glands — zero external leak points, reduced maintenance requirements.
- Size Range: 2" – 48"
- Pressure Class: Class 150 – 1500
- Body Material: WCB, CF8, CF8M
- Standards: API 594, API 6D
Manufactured to International Pipeline Standards
Every PANS pipeline valve is designed, tested, and documented to meet the regulatory requirements of the world's most demanding energy markets — from North American pipelines to CIS trunk systems and Middle Eastern refineries.
API 6D / ISO 14313
Every API 6D certified valve undergoes independent pressure integrity testing, including hydrostatic shell test, seat leakage test, and anti-static verification — giving EPC contractors and operators a single, auditable compliance record.
Fire Safe — API 607 / API 6FA
All applicable fire safe valve designs have been third-party tested to confirm the integrity of metal-to-metal seats under post-fire conditions, protecting pipeline infrastructure when polymer seats are compromised.
NACE MR0175 / ISO 15156
For sour gas and H₂S-containing service, materials are specified and tested per NACE MR0175 to prevent sulfide stress cracking — mandatory for upstream and midstream environments with ≥ 0.05 psi H₂S partial pressure.
ISO 9001 / ISO 14001 / ISO 45001
PANS holds triple ISO certification covering quality management, environmental management, and occupational health & safety — ensuring every production batch is traceable from raw material to final inspection.
TS Grade-A Special Equipment License
China's mandatory manufacturing license for pressure pipeline components, confirming PANS' legal and technical qualification to manufacture valves for pressurized service.
Multi-Standard Production
PANS organizes production under ANSI/ASME, API, DIN (German), GOST (Russian), and ISO standards — enabling supply to international EPC projects without re-engineering.
Designed for Zero Failure in the Most Demanding Environments
Zero Fugitive Emission Design
Bellow Sealed Globe and Gate Valves replace conventional packing glands with a fully welded bellows assembly — achieving ISO 15848 low fugitive emission compliance and eliminating the primary source of valve stem leakage in toxic or flammable service.
Corrosion-Resistant Material Matrix
PANS offers a full material matrix: WCB (carbon steel) for general service, CF8/CF8M (316 stainless) for corrosive fluids, LCB/LC3 for cryogenic service, and Monel/Inconel/Duplex alloys for aggressive sour gas environments. NACE MR0175 compliance is standard for sour service grades.
Actuator-Ready, Automation-Compatible
Every PANS automated pipeline valve is supplied with standardized ISO 5211 mounting flanges, enabling direct mounting of electric, pneumatic, or hydraulic actuators — no adapter plates, no custom machining. Smart positioners and limit switches can be pre-fitted at the factory for IIoT-ready pipeline systems.
Double Eccentric Low-Torque Plug Valve
The PANS orbit plug valve and double-eccentric designs use an off-center pivot geometry that lifts the sealing surface clear of the seat before rotation begins — eliminating wear on every cycle, reducing operating torque by up to 60% versus conventional plug valves.
Self-Lubricating Bearings
Plug and ball valve stems are fitted with self-lubricating composite bearings — no external grease required. This eliminates a routine maintenance task in remote or unmanned pipeline stations and reduces the risk of bearing seizure in cold-climate deployments.
Full Bore & Piggable Design
PANS full bore gate valves and ball valves maintain a through-bore equal to nominal pipe ID, allowing intelligent pipeline inspection gauges (PIGs) to pass freely — a non-negotiable requirement for long-distance natural gas transmission operators.
Trunnion-mounted seat design ensures load is supported independently of line pressure, enabling low-torque operation at Class 2500.
DBB cavity between the two seats can be independently vented via the bleed port, enabling safe maintenance isolation without full line shutdown.
