Compact Ball Valves

Compact Ball Valves

We provide Compact Style Ball Valves that are designed to provide considerable space and weight savings when compared to a traditional flanged end ball valve.

Thanks to our high-integrity design, we have supplied valve solutions to global customers for many years, custom-built to their individual requirements. Compact Ball valves have proven their worth in many applications.

Available in both floating and trunnion ball designs, the valve utilizes proven ball valve technology and can be supplied with either manual or automated actuation.

Product Overview

The design features include;
• Bi-Directional Ball Valves with soft or metal seats.
• Swivel flange type construction, with butt weld pipeline connections.
• Floating Ball or Trunnion mounted design.

Compact Light-Weight Design
Provides space and weight saving on platforms, reduced shipping and handling costs and minimal structural support.

Threaded Valve Insert
Designed to take full working pressure, which does not rely on the mating flange to hold internals.

Swivel Flanges
Designed to allow hubs to be welded into line before split rings and flanges are fitted. The valve can be fitted with no additional ‘springing’ of pipework.

Firesafe Design
O-ring seals and metal-to-metal contact on all static joints, graphite rings provide additional resistance to leakage in the event of a fire.

Other Design Features
Anti-blow out stem design shouldering on the body (rather than the bonnet), Automatic cavity relief, Low friction dry stem bearings to minimize operating torques and maximize cycle life. Valves can be supplied with a mounting plate in accordance with ISO 5211 for actuator attachment.

Reliable Isolation and Safety

Double Block and Bleed Valves offer true isolation, ensuring maximum safety by preventing leakage between isolated sections.

Compact and Efficient Design

These valves provide a space-saving solution, integrating two independent ball valves into one compact body for easy installation.

Built for Harsh Environments

Engineered for high-pressure applications, our DBB valves are designed to perform reliably under extreme conditions, reducing maintenance needs.
