The Lift Check Valves are designed to suit multiple applications; ideally where flow characteristics are such that it requires better flow control. Our specialized design on lift check valve helps to prevent flow reversals.

Forged Steel Valves are available in forged carbon steel, alloy steel and stainless steel materials with sizes ranging from 15 mm to 50 мм. These Valves are available in full port and reduced port type openings, and typically available in socket weld ends. Flanged or butt-weld ends can be provided in case of specific requirements. All valves are manufactured in accordance with the latest industry standards.

Forged Steel Lift Check Valves:

• Seat rings are a part of Valve trim. These are flared into the Valve body and fitted into place, thus forming sealing with body. Seating surfaces are machined, ground & lapped to obtain maximum sealing efficiency.
• Stem is part of Valve trim. Stem is provided with the integral backseat shoulder which mates with the integral backseat of bonnet.

Характеристики :

• Body and bonnet is designed as per the dimensional requirements of standards such as API 602, ISO 15761 and ASME B16.34.
• Bonnet is having integral backseat and consists of stuffing box, designed as per specification of API 602 and ISO 15761.
• Seat rings are integral and hard faced
• Stem has double start ACME Thread for smooth and fast operation

Преимущества :

• Smooth and fast operation
• Sturdy design so as to withstand rough operational conditions of Check Valves
• Manufacturing with advanced processes for best results and longevity
• Excellent sealing efficiency
