The top-entry ball valve is designed for easy maintenance and reliable performance in various industrial applications. Featuring a top entry design, this ball valve allows for convenient access to internal components without removing the valve from the pipeline. This design simplifies inspection, repair, and replacement, reducing downtime and maintenance costs. Top-entry ball valves are widely used in industries where operational efficiency and ease of service are critical.
MECCO Top-Entry Ball Valves are designed and manufactured in accordance with API 608, API 6D, ISO 17292, and GB/T 12237. Pressure ratings include CL150, CL300, CL600, CL900, CL1500, and CL2500 (or PN16 to PN420). If other pressure classes are required, the design can be carried out according to ASME B16.34 or GB/T 12224. Operating temperature range: -29℃ to 150℃.
Size:
NPS2~~NPS48 (DN50~~DN1200), sizes beyond this range can be custom manufactured according to customer requirements.
Material:
Body material according to customer order requirements, can be cast or forged materials.
Internal parts/Stem:
Seat rings use soft sealing materials such as PTFE, RPTFE, PEEK, etc., or hard sealing materials made by overlay welding, surfacing welding, spraying, laser cladding, etc., like the ball; hardness, corrosion resistance, and wear resistance of the sealing surface can be customized according to working conditions or customer requirements; stem made of integral forged material or configured per customer requirements.
Structure:
One-piece integral body structure, fixed shaft, DBB, DIB-1, DIB-2 types, can also be designed as three-way or multi-way connections per customer requirements; non-standard structural length requires negotiation with the customer.
Operation mode:
Handle, worm gear drive, electric, pneumatic, electro-hydraulic, etc.
