INTRODUCTION

Leader forged steel check valve is to provide with single disc. With the force of medium, the disc will automatically open or close, When the media stops the flow, the disc will be closed under its own force. No manual intervention is involved in the whole process Check valve is mainly to prevent the media reverse flow and ensure one-way flow of media channels only. It prevents accidents while a sudden loss of power in the pipeline medium such as the power equipment like pump damages, and the medium reserve flow against power source.

• Design Std.: BSEN ISO 15761, ASME B16.34.
• Pressure Temperature Rating as per ASME B16.34, BSEN ISO 15761.
• Sturdy design for high-pressure & temperature service.
• Welded body-cover joints offer an additional level of safety against fugitive emissions.
• Piston / Disc is guided in the Cover assuring accurate return to seating to achieve leak tightness.
• Spring-loaded disc on check valves suitable for non-horizontal applications too available on request.
• Socket welded ends as per ASME B16.11.
• Butt weld ends as per ASME B16.25 available on request.
• Low-Temperature Carbon Steel & Austenitic SS forging for body and cover design qualified as per BS 6364 for Cryogenic service available on request.
• Valves can be offered to NACE MR-0175 and other special NACE requirements.
• Valves are available with IBR certification.
