Quality Industrial Valve Product Made in China J-Valves Control Gas Carbon Steel WCB 6'' 300LB 2PC Flanged Floating Ball Valve

Product Overview

Designed for general industrial use, this floating ball valve combines WCB carbon steel’s structural strength with a modular two - piece body. The flanged connections simplify installation in high - flow systems, while the floating ball design provides dynamic sealing under pressure. Suitable for non - corrosive media, it offers zero leakage and low - torque operation in pipelines requiring frequent switching.

Key Features

Modular Two - Piece Design for Easy Maintenance

The split - body construction allows field replacement of the ball, seats, or stem in ≤45 minutes without pipeline disassembly. This reduces maintenance downtime by 60% in power plants and water treatment facilities, where system shutdowns cost $150,000/hour. The design also enables quick cleaning of internal components in food & beverage processing.


Dynamic Sealing Under Pressure

A floating ball with self - adjusting PTFE seats compensates for pressure fluctuations, ensuring bidirectional bubble - tight sealing (ISO 5208 Class A). This is critical for oil refineries and gas distribution networks, where pressure surges can damage conventional valves. CFD analysis confirms consistent sealing even at 1.5x rated pressure, preventing product loss.


High - Temperature Performance

WCB carbon steel (ASTM A216) withstands temperatures up to 425°C, outperforming standard cast iron by 35%. This makes it suitable for steam lines in power plants, hot water systems in district heating, and asphalt production units. Independent tests show no creep deformation after 10,000 hours at 400°C.


Fire - Safe Compliance & Antistatic Features

Meets API 607 fire - safe standards with graphite packing and a stainless steel antistatic device. The latter prevents electrostatic buildup in flammable media like propane and ethylene, reducing ignition risks in storage terminals. Tests confirm zero leakage after 10 minutes of flame exposure, ensuring compliance with OSHA and EPA regulations.


Low - Torque Operation

A bevel gear mechanism reduces operating torque by 30% compared to manual valves, enabling single - operator operation even in 6" sizes. This is crucial for offshore platforms and remote pipelines, where accessibility is limited. The design also minimizes wear on internal components, extending service life to 15+ years.


Corrosion - Resistant Coatings

Optional fusion - bonded epoxy (FBE) coating (ISO 12944 - 5 C5 - M) provides 300% longer service life in aggressive environments compared to standard painting. Case studies show this coating prevents chloride - induced pitting in coastal power plants and sulfuric acid corrosion in fertilizer production.
