In oilfield drilling fluid control systems, check valves play a vital role in preventing backflow and reducing water hammer risk. AIFUEL introduces a high-performance, cost-effective check valve series designed for standard onshore conditions, supporting both standard flow direction (union first) and reverse flow direction (threaded end first), fully covering 2" to 3" manifold applications.
1. Flexible Dual Flow Direction Options
Two flow configurations meet most manifold layout requirements:

Standard Flow Direction: Union connection in front / valve body at the rear

Reverse Flow Direction: Threaded connection in front / valve body at the rear

2. Upgraded Forging Process

Valve body is made of 42CrMo alloy steel with strict quenching + high-temperature tempering treatment, achieving high strength, toughness, and fatigue resistance.

Valve plate is made of ZG2Cr13, quenched and tempered for enhanced hardness, wear resistance, and corrosion resistance.

3.Three Structure Options Available

Type	Application Scenario	Key Advantage
Top Cover Baffle	General medium cut-off	Easy maintenance
Inline Baffle	High-frequency operation	Extended fatigue life
Dart-Type	High flow velocity	Fast response speed
