FAQ
What is a valve ball used for in a ball valve?
A valve ball is the core opening and closing component of a ball valve. It controls fluid flow, cut-off, and flow regulation. Our factory produces high-precision forged valve balls with strict roundness tolerance ≤0.01mm, ensuring zero leakage and long service life for industrial pipeline systems.
What materials are available for forged valve balls?
We supply stainless steel 304, 316L, duplex F51/F53, super duplex, 17-4PH, Inconel 625, Hastelloy, Monel K400 and A105 carbon steel. All materials are fully spectrally inspected to meet API and international industrial standards.
What is the precision tolerance of your valve balls?
Our standard valve ball roundness tolerance is controlled within ≤0.01mm, surface roughness Ra ≤0.2μm. Every ball is 100% fully inspected by three-coordinate measuring equipment to guarantee high sealing performance.
Do you manufacture solid forged balls and hollow balls?
Yes. We produce both forged solid valve balls and hollow valve balls for floating and trunnion mounted ball valves. Custom size and weight are available according to customer valve design requirements.
Can you supply hard seal valve balls for high temperature service?
Yes. We provide hard seal valve balls with Stellite hard facing, TCC tungsten carbide coating and special heat treatment. Suitable for high temperature, high pressure and high wear industrial working conditions.
Do you support custom valve ball sizes and designs?
We fully support OEM and ODM customized valve balls, including special diameter, special hole shape, V-port, T-port, L-port and special connection dimensions. Custom drawings and samples are acceptable.
What pressure classes do your valve balls cover?
Our valve balls match pressure classes from Class150 to Class4500 and PN16 to PN420. Suitable for low pressure, medium pressure and high pressure pipeline engineering projects.
Are your valve balls suitable for oil and gas industry?
Absolutely. Our high precision forged valve balls are widely used in oil and gas, petrochemical, natural gas pipeline and LNG projects. All products meet API and industrial quality requirements.
Do you provide soft seal and hard seal two types of valve balls?
Yes. We produce both soft seal valve balls for general pipeline and hard seal valve balls for high temperature and high wear conditions. Both types ensure stable sealing and zero leakage.
What testing do you do for every valve ball?
We conduct full dimension inspection, roundness test, surface roughness test, material spectral analysis, pressure test and visual appearance inspection. Each batch comes with official inspection reports.
Can you make Inconel 625 and special alloy valve balls?
Yes. We specialize in high-end alloy valve balls including Inconel 625, Hastelloy, Monel and 17-4PH. These special alloy balls are widely used for strong corrosion and high temperature working conditions.
What is your valve ball production capacity?
Our monthly production capacity reaches more than 1 million pieces of various valve balls. Stable mass production and fast delivery for bulk orders and project orders.
Do you have ISO and CE certification for valve balls?
Yes. Our factory has ISO9001, CE and relevant industrial certifications. All production and quality management strictly follow international manufacturing standards.
What is your delivery time for valve ball orders?
Normal standard size valve balls delivery time is 15-25 days. Customized and special alloy balls take 30-40 days according to order quantity and processing difficulty.
Do you provide sample order for quality checking?
Yes. We support small batch sample orders for customers to test quality, precision and sealing performance before formal bulk cooperation.
Where is your valve ball factory located?
Our professional valve ball manufacturing factory is located in Wenzhou, Zhejiang China, the professional valve and valve ball industrial cluster area with complete supply chain and advanced processing equipment.
Do you export valve balls to overseas markets?
Yes. Our valve balls are exported to Europe, America, Middle East, Southeast Asia, South America and other international markets for many years with stable quality and good reputation.
What machines do you use to produce valve balls?
We adopt imported Mazak CNC machines, automatic grinding machines, professional lapping machines and three-coordinate testing equipment to ensure high precision and stable product consistency.
Why choose your factory for valve ball supplier?
We are professional high precision forged valve ball manufacturer with strict tolerance, full inspection, stable quality, fast delivery and professional custom service. We focus only on valve ball production, more professional and more reliable.
How to get a quick quotation for valve balls?
Customers can provide size, pressure class, material, quantity and drawing requirements. We will provide formal detailed quotation within 24 hours with complete product specification and delivery arrangement.
