Versatile Design for Diverse Applications

Built to meet various industrial demands, our Extended Stem Ball Valves support installation in vertical or horizontal orientations and excel in underground, insulated, and cryogenic pipeline operations. Full bore structure ensures unobstructed flow, and adaptability to ANSI, DIN, or JIS flange standards allows seamless integration across global projects. Each valve is crafted with attention to durability and corrosion resistance.

Reliable Performance with Advanced Safety Features

Fire-safe construction and anti-static devices are standard, providing enhanced protection in high-temperature or hazardous environments. Zero leakage (bubble tight) is achieved with PTFE or graphite sealing, mitigating operational risks and maintenance costs. Locking devices can be selected for added security, ensuring valve position remains fixed during critical processes.

Customization for Project-specific Needs

Our valves offer customizable stem extension lengths to accommodate unique site requirements, including deep insulation or underground placement. Choose from a selection of body types, materials, and end connections to align with project scope and media requirements, guaranteeing a perfect fit and robust operation every time.

FAQ's of Extended Stem Ball Valve:

Q: How can the stem extension length of the Extended Stem Ball Valve be adapted for specific project requirements?

A: The stem extension length is fully customizable during the manufacturing process to suit distinct installation challenges, such as deep insulation, underground placement, or remote operation. Specify your required extension, and we tailor each valve to meet those exact dimensions for optimum accessibility and operability.

Q: What benefits does the zero leakage (bubble tight) design provide?

A: Zero leakage ensures absolute sealing integrity, preventing media escape and reducing environmental or asset loss. This superior sealing, achieved with PTFE or graphite, lowers maintenance frequency, enhances safety and protects system reliability, especially valuable in critical water, oil, or gas applications.

Q: Where are Extended Stem Ball Valves typically used, and what media are compatible?

A: These valves are widely employed in underground pipelines, insulated conveyance systems, cryogenic service, chemical industries, and petrochemical plants. They handle water, oil, and gas within a temperature range of -29C to 180C, making them ideal for versatile industrial environments.

Q: What is the process for selecting the suitable body material and connection type?

A: Selection depends on the project's media, pressure, temperature, and required durability. We offer ASTM A216 WCB for carbon steel applications and ASTM A351 CF8/CF8M for stainless steel environments. End connections can be chosen from flanged, threaded, or socket weld types, all adhering to ANSI, DIN, or JIS standards for global compatibility.

Q: How does the anti-static device and fire-safe design increase operational safety?

A: The anti-static device dissipates static electricity generated by fluid motion, reducing the risk of ignition or explosion. Fire-safe design ensures valve functionality is maintained during fire exposure, providing critical safety and compliance with industrial standards like API 6D and BS 5351.

Q: When should a locking device be added to the valve configuration?

A: A locking device is recommended when fixed valve positioning is needed, such as in hazardous or high-security environments, to prevent unauthorized operation or accidental movement during system maintenance or emergency situations.

Q: What advantages does full bore structure offer in this ball valve?

A: Full bore construction minimizes flow restriction and pressure drop, enabling maximum efficiency for process control. It permits pigging operations and reduces turbulence, which results in improved pipeline longevity and reduced operational costs.
