Full Welded Ball Valve

INTRODUCTION

These types of valves are being used for natural gas pipeline pig stations, Compressor and Measuring stations, RMS Pressure Regulating and Measuring stations and Underground & Aboveground applications. Conformity to MR0175 requirements and PSL2 level can be obtained upon request and can be manufactured with different materials.

Valves are manufactured with full port or reduced port. Bore diameters comply with API 6D standards.

Connection pups are welded upon request with dimensions determined by manufacturer and customer.
