Key Features
-
Robust Construction
Crafted from high-strength alloy materials with anti-corrosion treatment, the valve body maintains structural integrity within a temperature range of -20℃ to 150℃, compatible with water, oil, gas, and other common media.
-
Ergonomic Operation
The contoured handle design reduces rotational torque by 30% compared to conventional models, while clear graduation markings provide intuitive flow control. Tactile feedback ensures precise adjustment.
-
Enhanced Sealing
Multi-layer sealing components combined with precision-machined valve seats minimize leakage risks. The self-aligning valve core design maintains consistent performance even after prolonged use.
-
Adaptable Configuration
Available with flange or threaded connections for horizontal/vertical installation. Compact dimensions optimize space utilization in complex pipeline arrangements.
Typical Applications
Ideal for industrial cooling circuits, energy distribution pipelines, water treatment facilities, and HVAC systems. Particularly suited for scenarios requiring frequent flow adjustments or routine maintenance.
Usage Guidelines
Periodically inspect valve surfaces and seals. Avoid excessive torque during operation. Recommended to install upstream filters for contaminant protection. Verify flow direction alignment before commissioning.
