1. Product Description

The high-pressure ball valve is a core fluid control switch device specially designed for harsh high-pressure working conditions of onshore oilfields, offshore platforms, drilling manifolds, cementing and fracturing operations, and petrochemical pipeline systems. Adopting a spherical rotary switching structure, the valve controls the full opening and closing of fluid passages through 90-degree rotation of the precision forged ball body, realizing fast cut-off, circulation and shunting of oil, natural gas, water and various industrial chemical media. Compared with conventional medium and low-pressure valves, this high-pressure ball valve features ultra-high pressure resistance, excellent sealing stability and strong environmental adaptability, making it the preferred control equipment for high-risk and high-load oil and gas fluid systems.
The product adopts an integral forged steel structure with one-piece or three-piece body design, featuring high overall structural rigidity, no deformation under ultra-high pressure and outstanding vibration resistance. It supports two mainstream structural types: floating ball and trunnion-mounted ball. The floating ball structure is compact and flexible for medium and small-caliber pipelines, while the trunnion-mounted ball design bears large axial pressure, suitable for large-diameter and super high-pressure working conditions. Equipped with high-performance metal hard sealing and composite soft sealing materials, the valve achieves bidirectional zero-leakage sealing effect, effectively avoiding medium leakage caused by pressure impact, temperature fluctuation and long-term vibration fatigue.
This series of ball valves supports manual, pneumatic and electric multi-control modes, with flexible and labor-saving operation, fast switching response and stable flow regulation performance. All internal flow channels are precisely polished with smooth inner walls, low fluid resistance and no turbulent pressure loss. The valve body undergoes integral forging and heat treatment to enhance structural toughness and corrosion resistance. It can operate stably for a long time in extreme environments such as high pressure, low temperature, high salinity and corrosive media, widely used in wellhead control, pipeline switching, manifold distribution and offshore engineering fluid management, ensuring safe and efficient operation of the entire oil and gas production system.

Frequently Asked Questions (FAQ)

Q1: What are the advantages of high-pressure ball valves compared with ordinary valves?
A1: High-pressure ball valves adopt integral forged structure with high pressure resistance and strong deformation resistance. Featuring fast 90-degree switching, low fluid resistance and bidirectional zero-leakage sealing, they can adapt to ultra-high pressure and harsh marine working conditions. They solve the problems of easy leakage, slow response and short service life of ordinary valves in oilfield high-pressure systems, ensuring long-term stable operation.
Q2: How to choose between floating ball and trunnion ball type?
A2: Floating ball ball valves are suitable for small-caliber and medium-high pressure pipelines with flexible operation and low cost. Trunnion-mounted ball valves are designed for large-caliber and super high-pressure working conditions, with stronger bearing capacity and better anti-vibration performance, ideal for offshore platforms and fracturing equipment systems.
Q3: Can customized sizes and control modes be provided?
A3: Yes. We support full customization of caliber, pressure grade, material, connection mode and control system. Manual, pneumatic and electric driving modes are optional to meet automatic and remote control requirements of different engineering projects.
Q4: What certification and test documents can be provided?
A4: Our products comply with API 6D and ASME international standards, and have passed CE, ISO 9001 and marine classification society certifications. We can provide complete material reports, hydraulic test certificates, NDT detection reports and export qualification documents for project acceptance and customs clearance.
Q5: What is the delivery cycle and after-sales service?
A5: Standard models are in stock with delivery within 7–10 working days. Customized products take 15–25 working days. We provide remote technical guidance, on-site installation training and lifelong spare parts supply to solve on-site operation and maintenance problems efficiently.
