Product Description

Sea Water Butterfly Valves - Marine-Grade Flow Control Solutions

ZTVK Fluid Control Equipment conveys enterprise-grade sea water butterfly valves built for marine applications. Our valves highlight a "twofold unpredictable + angled seal" plan that diminishes opening torque by 30% and amplifies operational life past 50,000 cycles. With working weights up to PN16 and sizes extending from 1.5" to 48" (DN40-DN1200mm), these valves work proficiently in temperatures from 0℃ to 80℃. Built with corrosion-resistant materials counting duplex steel and specialized EPDM/VITON seating, our butterfly valves outflank conventional cast press options in requesting marine environments.

Why Choose Our Sea Water Butterfly Valves?

Advanced Engineering Design

Our butterfly valves join cutting-edge innovation particularly planned for challenging marine conditions. The spherical-processed valve circle edges experience manual cleaning, guaranteeing smooth operation and expanded seal life. This one-piece plan avoids tidy molecule collection and bacterial development - vital for marine sanitation systems.

The inventive "lean plate plan" increments Cv values by 50% compared to ordinary spindle-through plans. This improvement conveys predominant weight recuperation capabilities whereas keeping up lower weight drops, making our valves really energy-efficient arrangements.

Superior Corrosion Resistance

Marine environments demand exceptional material performance. Our sea water butterfly valves utilize premium materials including:

  • Body Materials: Ductile Iron (DI/QT450)
  • Disc Options: DI, CF8, CF8M, and Aluminum Bronze
  • Seat Materials: EPDM, NBR, PTFE, and VITON

The valve stem and disc surfaces can be coated with nitrile rubber or ethylene propylene rubber, providing additional protection against metal surface erosion and corrosion from saltwater exposure.

Flexible Operation Options

We offer multiple actuation methods to suit your specific application requirements:

  • Manual: Hand lever and worm gear operation
  • Automated: Pneumatic and electric actuators
  • Connection: Wafer type design
  • Standards: ISO5211 compliance (PN10/PN16/125LB/150LB/JIS5K/JIS10K/JIS16K)

Key Performance Features

Quick Operation & Energy Efficiency

The 90-degree opening and closing mechanism ensures rapid valve operation. Minimized operating torque requirements make manual operation effortless while reducing actuator power consumption in automated systems. This design translates to significant energy savings in large-scale marine applications.

Exceptional Sealing Performance

Our valves achieve near-zero leakage through precision-engineered sealing systems. The flow characteristics closely approximate linear performance, providing excellent flow control capabilities essential for marine systems requiring precise flow regulation.

Versatile Media Compatibility

These robust valves handle diverse marine applications including:

  • Fresh water and seawater systems
  • Ballast water management
  • HVAC applications
  • Fire protection systems
  • Various oils and chemical solutions
  • Food and pharmaceutical processing aboard vessels
