DHD340A Hammer

The DHD340A DTH Hammer is a specific variant of the DHD340 model of Down-The-Hole (DTH) hammers. In this case, the "A" designation indicates that the DHD340A DTH Hammer is designed without a foot valve.

A foot valve is a component typically found in DTH hammers that helps to regulate the flow of compressed air or drilling fluid during drilling operations. It acts as a check valve, allowing air or fluid to flow into the hammer but preventing its backflow. The foot valve helps maintain consistent pressure and airflow within the hammer, which contributes to efficient drilling performance.

DHD340 DTH Hammer with Foot Valve:
Foot Valve: The DHD340 DTH Hammer with a foot valve incorporates a foot valve mechanism. The foot valve acts as a check valve, allowing the compressed air or drilling fluid to flow into the hammer while preventing backflow. This mechanism helps maintain consistent pressure and airflow within the hammer, contributing to efficient drilling performance.

Effective Sealing: The foot valve ensures effective sealing when the compressed air or drilling fluid enters the hammer. It helps prevent the loss of energy or pressure during the drilling process, optimizing the hammer's impact energy transfer to the drill bit.

Enhanced Performance: The presence of a foot valve in the DHD340 DTH Hammer facilitates efficient drilling in various rock formations by maintaining constant pressure and reducing energy loss. It enables reliable performance and provides stability during drilling operations.

DHD340A Hammer without Foot Valve:
Alternative Flow Regulation: In the DHD340 DTH Hammer without a foot valve, alternative mechanisms or designs are employed to regulate the flow of compressed air or drilling fluid. These mechanisms may include different types of valves or structures within the hammer to control the airflow.

Simplified Design: The absence of a foot valve simplifies the design of the DHD340 DTH Hammer, potentially reducing manufacturing complexity and costs.
