ball valves

The ball valve is an efficient and reliable fluid control device, known for its simple design and excellent sealing performance. Its core part is a spherical valve core, which can be turned 90 degrees to achieve switch control, and the operation is intuitive and fast.

The valve's advanced sealing architecture integrates reinforced PTFE seats and stem packing, achieving bubble-tight shutoff compliant with API 598 standards. This bidirectional sealing capability ensures reliable performance in both high-pressure (rated to PN100/Class 600) and extreme temperature applications (-29°C to 200°C).

Key Features:

Zero-Leakage Integrity: Multi-stage stem sealing system with anti-blowout design

Operational Efficiency: Low-torque operation with <5 Nm actuation force (manual models)

Material Versatility: Available in 316SS, brass, and duplex steel configurations

Full Port Design: 100% bore geometry minimizes turbulence for viscous media

Multi-Driver Compatibility: Adaptable to manual lever, pneumatic actuator, or electric motor interfaces

Accessories

SGON valves feature sealing strips made of RPTFE, offering superior high-temperature resistance, chemical corrosion resistance, and a longer service life compared to standard PTFE. Additionally, SGON uses 304 stainless steel for bolts, nuts, and gaskets, ensuring greater durability and stability than the commonly used 201 stainless steel.

Processing

SGON valves use advanced automated lathe processing technology to ensure higher precision and stability. This automated production process not only improves production efficiency, but also reduces labor costs, thereby ensuring product quality while providing more competitive prices.

Frequently Asked Question

Do your ball valves comply with international standards (e.g. API, ISO, CE, etc.)?

Our ball valves strictly follow international standards: API 6D (oil and gas industry valve standard) ISO 5211 (actuator installation standard) CE/PED (EU Pressure Equipment Directive certification) Fire safety certification (API 607/API 6FA) All products are tested by third party laboratories and full certification documents are available.

What materials are used for the valve body, seat and ball? Are they suitable for corrosive media?

Valve body material: carbon steel (WCB), stainless steel (CF8M/316SS), duplex steel, etc., optional ANSI or DIN standards. Seal material: PTFE, reinforced PTFE, PPL, metal seal (high temperature and high pressure conditions). Corrosion resistance: For acidic environments (e.g., H2S, CO₂), we offer material options in accordance with NACE MR0175, and we support coated anti-corrosion treatments (e.g., epoxy coatings).

What is the maximum working pressure and temperature range of a ball valve?

Pressure Rating: PN10~PN420 (National Standard) / Class 150~2500 (American Standard). Temperature range: Standard ball valves are suitable for -29°C to +200°C; high-temperature type (metal-sealed) can be extended to +425°C, and low-temperature type (deep-cooled) is suitable for -196°C (LNG and other working conditions).

Does the valve leakage rate comply with ISO 5208 or API 598?

Yes. We offer the following leakage ratings: Soft seal: to ISO 5208 Class A (zero leakage). Metal Sealed: To API 598 with a leakage rate of ≤100ppm. All valves are factory tested for 100% air tightness.
