Ball Valves

LPK11 High Pressure Hydraulic Ball Valve

LPK11 Two-Way Hydraulic Ball Valve is a high-pressure, quarter-turn isolation valve designed specifically for demanding hydraulic circuits, providing fast, leak-free on/off flow control and unobstructed full-bore flow in heavy-duty industrial and mobile equipment applications.

Product Description

The two-way hydraulic ball valve is engineered to safely regulate and isolate the flow of hydraulic oils and fluids in high-pressure systems. Utilizing a robust floating ball design with a central bore, the valve achieves rapid 90-degree open/close actuation. When aligned, the full-bore configuration ensures unrestricted flow with minimal pressure drop; when rotated perpendicular to the flow path, system pressure forces the ball against precision-machined POM or PTFE seat seals, delivering a bubble-tight shutoff.

Constructed from high-strength carbon steel or stainless steel with protective zinc or nickel plating, the valve body is designed to withstand continuous operating pressures up to 500 bar (7,250 psi) and temperatures ranging from -20°C to +100°C. Available in compact block-type or sleeve-type designs with threaded (BSPP, NPT) or cutting-ring connections, it integrates seamlessly into complex hydraulic manifolds and piping systems.

The series includes BK, MK, KH, BKK, KHZ, KHDL type high pressure ball valves.

Key Features

High-Pressure Capability: Rated for continuous operation up to 500 bar (7,250 psi), ensuring reliable performance in extreme hydraulic environments.
Fast Quarter-Turn Actuation: 90-degree manual handle operation allows for rapid emergency shutoff and easy position indication.
Unrestricted Full-Bore Flow: Straight-through port design minimizes pressure loss, turbulence, and energy consumption.
Pressure-Assisted Sealing: Floating ball design utilizes line pressure to push against the seat ring, ensuring zero-leakage, bubble-tight closure.
Compact & Rugged Construction: Forged steel body with anti-corrosion surface treatment, optimized for space-constrained hydraulic panels and manifolds.
Bidirectional Flow: Symmetric internal geometry allows installation in either flow direction without performance loss.
ISO 5211 top mounting pad: Available bracket for easy retrofitting of pneumatic, electric, or hydraulic actuators for automated control.
