Complete Industrial Valve Product Portfolio

XINTAI Valve Group’s product line is organized into 8 core categories, engineered for high-durability and corrosion-resistant flow control in demanding industrial installations.

Ball Valves: V-Port Ball Valve Vs. Standard Ball Valve Comparison

Configurations Available: Floating / Trunnion Mounted / Double Block and Bleed / Fully Welded / Casting / Forged / Metal Sealing / Soft Sealing / Top Entry / V-Notch (V-Port) / Wafer.

A standard ball valve (floating or trunnion mounted) uses a spherical bore for full-open or full-closed pipeline isolation. The floating design utilizes fluid pressure to press the ball against the seat, preventing low-pressure leaks, while the trunnion design fixes the ball on bearings to lower operating torque and avoid jamming under high pressure — both configurations conform to API 6D standards for validated sealing safety in oil and gas pipelines and refineries.

By contrast, a V-port ball valve (V-notch design) replaces the standard spherical bore with a V-shaped notch cut into the ball, enabling precise, linear flow throttling rather than simple on/off isolation. This structural difference means:

• Standard ball valve: Optimized for tight shutoff and binary isolation of high-pressure lines, minimizing leakage risk in oil and gas pipeline service.
• V-port ball valve: Optimized for modulating and controlling variable flow rates, making it suitable for applications requiring adjustable throttling rather than pure isolation.

Both configurations benefit from XINTAI’s metal-to-metal sealing options for high-temperature service and specialized Al-Bronze materials for seawater resistance.

Customer Validation:

• Petronas Supply: Valve solutions tailored to competitive regional markets in Southeast Asia.
• Petrobras Partnership: High-specification valves supplied for South American petrochemical projects.

Gate Valves: Wedge / Slab / Pressure Seal / Cast Steel / Forged / Rising Stem / Non-Rising Stem / Knife

Pipeline isolation valves for full-bore flow control, addressing media leakage and solid accumulation in lines. Wedge gate design stops fluid flow reliably; knife gate design cuts through slurries, pulp, and solid contaminants; bellow seal design eliminates stem packing leakage via a secondary metallic barrier. Applied in wastewater treatment, chemical processing, and pulp and paper industries.

Globe Valves: Pressure Seal / Bellows Seal / Cast Steel / Forged / Angle / Y Type

Throttling and flow regulation valves that integrate with pneumatic or electric actuators to automate high-frequency throttling and reduce manual operations in power plants and chemical facilities.

Butterfly Valves: Centerline / Double Offset / Triple Offset / Wafer / Lug / Flanged / PTFE Lined / Metal Seated

Compact rotary valves for isolation and throttling. Double eccentric geometry offsets the shaft from the sealing seat to reduce friction; triple eccentric geometry adds a third angular offset for frictionless metal-to-metal sealing suited to district heating and cooling water systems.

Check Valves: Swing / Wafer / Dual Plate / Lift

Self-acting backflow prevention valves. The swing design automatically opens with flow pressure and closes when flow stops, protecting upstream pumps in power generation and pipeline systems.

Strainers: Y / T / Basket

Pipeline filtration devices using a removable basket design to collect solid debris and protect downstream valve seats in industrial cooling systems and petrochemical refineries.

Safety Valves

Overpressure protection valves with automated relief action that opens instantly when pressure limits are exceeded, preventing catastrophic failure in steam boilers and pressure vessels.

Cryogenic Valves: Cryogenic Ball / Gate / Globe / Check / Butterfly Valves

Low-temperature fluid handling valves featuring an extended bonnet that elevates stem packing away from cryogenic fluid, preventing seal freezing and failure in LNG storage and transportation terminals.
