Wafer Check Valve, Butterfly Valve Supplier

Reliability, Backed by Facts

JRVAL specializes in Mid-to-High-End Butterfly & Wafer Check Valves. Our valves are strictly inspected according to ISO 5752. They have worked normally in the following harsh environments without leakage or damage:

In Arctic oil fields (-50°C) and Siberian pipelines, standard butterfly valves fail due to brittle fracture from low-temperature embrittlement. Our LCC LC1 ultra-low-temperature steel addresses this through three innovations: -196°C cryogenic treatment combined with 72-hour tempering stabilizes microstructure; Ni/Mo alloy optimization enhances impact toughness by 30% at -196°C; and nanoscale grain boundary control prevents cold cracking during extreme contraction. These advancements enabled 100 thousands+ fault-free hours in Arctic LNG projects and the Siberian gas pipeline, redefining cold resistance standards.

In Saudi Arabia’s Khurais oil fields, conventional seals softened at 160-180°C, becoming a major source of pipeline leakage. Our solution combines specialized FKM (e.g., 71% fluorine) with Y₂O₃ as an H₂S scavenger/stabilizer (enhancing thermal/chemical resistance), a 45° conical seal design improving stress distribution, and thousands of thermal shock cycles (180°C/12MPa) achieving zero leakage (API 598 compliant). Deployed in an initial batch of 320 valves, this technology delivered 19 months of continuous operation and saved $2.7 million in maintenance costs, proving reliability under extreme desert conditions.

In Kazakhstan’s nitric acid pipelines (pH 0.5), conventional valves corroded within six months, costing $500,000+ annually. Our innovations include Hastelloy C-276 valve plates (15-16% Mo, 4-7% Cr) resisting 50-55% nitric acid up to 400°C, triple eccentric metal seals reducing torque by 30%, and PTFE with 25% glass fiber reinforcement (friction coefficient 0.05) withstands 10m/s acid flow. These solutions cut Kazakhstan’s annual maintenance costs by $500,000, doubling valve lifespan.

Deep-sea oil & gas transport presents an ‘impossible triangle’: high pressure (>1000psi), H₂S corrosion, and fire safety demands. Our solution features valves engineered for these extremes. Utilizing advanced alloys and sealing designs (e.g., triple-offset, dual seals), our valves achieve zero leakage even above 1000psi. Proven in deep-sea projects, they deliver long service life and API 607/6FA certified fire safety, guaranteeing reliability and operational safety.

Beyneu-Shymkent gas pipeline’s 2023 fire destroyed 612 valves, highlighting traditional butterfly valves’ flaws: methane permeation (5×10⁻⁵ cm³/cm²·s at 10MPa) and fire failure (8000cc/min leakage after 30min combustion). Our dual defense solution features API 609 fire-tested valves maintaining <500cc/min leakage at 750℃, and zero-leak seals with nano-coatings achieving <1×10⁻⁶ cm³/cm²·s permeation. In Kazakhstan, our valves prevented $120M explosion loss, extended maintenance intervals 10x.

In Nigeria’s offshore oil sector, a refinery urgently needed 45°-angled butterfly valves with Hastelloy C-276 for 120°C sulfuric acid streams—no supplier could meet specs. JRVAL’s integrated foundry-to-assembly process delivered 24 units in 8 weeks: 3D-printed molds ensured ±0.1mm angular precision, while 22% molybdenum alloy resisted 3.2mm/year corrosion. Post-API 609 testing, zero leakage at 1500LB pressure cut annual maintenance costs by 35%.
