COVNA HK60-Z-S Multi-turn Electric Actuator Knife Gate Valve
Key Features
Precise Shutoff: A multi-turn electric actuator with a hard-sealed gate achieves zero-leakage shutoff, ensuring process safety.
Low Power Consumption, High Efficiency: Utilizing an advanced motor and gear drive system, operating power consumption is significantly reduced, extending maintenance intervals.
Modular Design: The valve body, motor, and control unit can be quickly disassembled and assembled, enabling rapid on-site maintenance and upgrades.
Weatherproof and Explosion-Proof: Standard IP55 outdoor dust and water resistance, with options available up to IP65, IP67, and IP68. Explosion-proof versions are also available for use in non-excavated areas of coal mines (d⁰) or explosive atmospheres in industrial plants (d¹BT4).
Various Materials Available: Body: Cast Iron, 304/316 Stainless Steel; Seals: PTFE, NBR, EPDM, VITON
