Top Entry Ball Valves
What is it?
A top entry ball valve is designed so that the internal parts (ball, seat, and stem) can be accessed and repaired by removing the top cover, without removing the valve from the pipeline.
Technical Specifications
- Sizes: Typically 2” – 60”
- Pressure Rating: Class 150 – 2500
- Body Material: Carbon Steel, Stainless Steel, Duplex, Super Duplex
- Design Standard: API 6D / ISO 14313
Applications
Used in industries where inline maintenance is essential such as oil & gas pipelines, chemical plants, and power generation.
Mounted Ball Valve
What is it?
A mounted ball valve refers to a fixed design (often trunnion-mounted) where the ball is supported by bearings, reducing torque and making it suitable for high-pressure applications.
Technical Specifications
- Sizes: 2” – 48”
- Pressure Rating: Class 150 – 2500
- Body Material: Forged or Cast Steel
- Operation: Manual, Gear, Pneumatic, or Electric Actuator
Applications
Ideal for high-pressure pipelines, offshore platforms, and refineries.
High Performance Butterfly Valve
What is it?
A high-performance butterfly valve is designed to handle higher pressure and temperature than standard butterfly valves, using a double-offset disc design.
Technical Specifications
- Sizes: 2” – 48”
- Pressure Rating: Class 150 – 600
- Materials: Carbon Steel, Stainless Steel, Duplex
- Design: Double Offset
Applications
Commonly used in HVAC, power plants, marine applications, and chemical processing.
Combined D.B. & B. Ball Valve
(Double Block and Bleed Ball Valve)
What is it?
This valve provides two sealing surfaces (double block) and a means to bleed or drain the cavity between them, ensuring zero leakage isolation.
Technical Specifications
- Sizes: 2” – 36”
- Pressure Rating: Class 150 – 2500
- Materials: Carbon Steel, Stainless Steel, Super Duplex
- Standards: API 6D, ASME B16.34
Applications
Used in pipelines, petrochemical plants, and refineries where tight shut-off and cavity relief are critical.
Combined Trunnion Ball Valves
What is it?
A trunnion-mounted ball valve uses additional mechanical anchoring of the ball, making it stable and reliable for large-size, high-pressure service.
Technical Specifications
- Sizes: 2” – 60”
- Pressure Rating: Class 150 – 2500
- Materials: Carbon Steel, Alloy Steel, Stainless Steel
- Actuation: Manual, Pneumatic, Hydraulic, or Electric
Applications
Suitable for crude oil and natural gas pipelines, power generation, and process industries.
Triple Offset Butterfly Valve
What is it?
A triple offset butterfly valve uses three different offsets in its design, eliminating friction during operation and providing bubble-tight shutoff.
Technical Specifications
- Sizes: 3” – 72”
- Pressure Rating: Class 150 – 900
- Materials: Stainless Steel, Duplex, Super Duplex
- Design: Metal-to-Metal Seal
Applications
Widely used in oil & gas, petrochemical, power plants, and applications requiring zero leakag
