description

The upgraded DH Foot Valve LD adopts optimized integrated valve body structure and thickened reinforced pedal base design. The internal precision valve core and high-toughness reset spring are strictly calibrated according to Doosan DH series hydraulic parameters, realizing sensitive oil circuit switching and rapid reset response. Compared with ordinary foot valves, the LD version enhances internal oil circuit smoothness, reduces hydraulic resistance, and avoids operational lag and unresponsive control caused by oil pressure blockage. The external pedal adopts anti-slip and anti-pressure structural optimization, which can withstand long-term frequent treading impact and heavy-load vibration without deformation or jamming. The overall valve body undergoes anti-rust and anti-fouling treatment, which can resist mud deposition, dust blockage and humid corrosion on the construction site. All finished LD foot valves pass strict hydraulic pressure test, reset sensitivity detection and assembly matching inspection, featuring stable pressure regulation, sensitive response and strong environmental adaptability, fully adapting to long-term high-frequency walking and swing operation of DH series excavators.

advantages

LD customized oil circuit optimization, perfectly matching the hydraulic logic of Doosan DH full-series excavators. It supports direct replacement of ordinary foot valves without pipeline modification or parameter debugging, realizing zero-error assembly and greatly improving control smoothness.
Upgraded reinforced pedal base structure enhances pressure resistance and impact resistance. It can withstand long-term frequent treading and construction vibration without structural deformation or pedal sinking, maintaining consistent operating feel for a long time.
Precision polished valve core and high-elasticity reset spring effectively solve the common problems of slow reset, jamming and oil circuit unsmoothness of ordinary foot valves. The hydraulic response is timely and sensitive, with no lag during walking and swing operation.
Low-resistance hydraulic design reduces foot treading force, realizing labor-saving operation. It effectively relieves foot fatigue caused by all-day frequent walking and swing actions, improving continuous construction efficiency.
The valve body adopts anti-fouling and anti-corrosion coating treatment, which can prevent dust and sediment from blocking the internal oil circuit. It maintains stable oil supply pressure in muddy and harsh environments, reducing equipment failure rate.
Long-life structural configuration reduces frequent replacement and maintenance caused by aging and damage of ordinary foot valves, lowering equipment operating costs and downtime loss, with higher comprehensive cost performance.

FAQ

Q1: What are the common failures of ordinary DH foot valves?
A: Standard foot valves are prone to spring fatigue and internal oil circuit blockage after long-term use, resulting in slow reset, pedal jamming, unresponsive swing and walking lag. Severe cases will cause continuous partial action and affect construction safety.
Q2: What is the upgrade advantage of LD version compared with ordinary foot valves?
A: The LD version optimizes the internal oil circuit and reset structure, featuring labor-saving operation, sensitive reset and strong anti-clogging ability. It solves the fatigue and jitter problems of ordinary models, and is more suitable for long-term high-frequency walking and swing working conditions.
Q3: Is the DH Foot Valve LD universal for all DH series models?
A: Yes. It is fully compatible with Doosan DH5, DH7, DH9 full-series small, medium and large excavators, with universal installation dimensions and hydraulic parameters, supporting direct replacement without adaptation adjustment.
Q4: Does replacing LD foot valve require professional hydraulic debugging?
A: No debugging is needed. The LD version completely follows the original factory hydraulic parameters and installation standards, realizing plug-and-play replacement, which can be completed quickly by on-site maintenance personnel.
Q5: Why does LD foot valve operate more labor-saving?
A: The LD version reduces internal hydraulic resistance through oil circuit optimization, matched with high-elasticity reset spring. The treading resistance is lower and the reset is faster, effectively reducing foot operating force and long-term operation fatigue.
