Product Characteristics
The MAW Series Worm Gear Actuator is designed for manual quarter-turn valve operations, employing robust worm gearboxes housed mainly in ductile iron, with optional cast iron. The input shafts utilize steel, with options for stainless steel material to suit corrosive environments. Bearings, coatings such as epoxy and PU, and powder-coated handwheels add protection and operational reliability.

Technical Specifications
Torque ratings range impressively from 100 Nm to 32,000 Nm, catering to an assortment of valves in different sized applications. Stroke adjustment allows ±5º tiny movement corrections. Different IP ratings safeguard against environmental ingress, and operating temperatures span a wide range including extreme cold or heat.

The product matrix covers various models (e.g. MAW-012, MAW-2400, MAW-3200) and options such as single and double-stage helical gear reductions that offer enhanced gear ratios and torque multiplication for heavy valve operations.

Handwheel Options and Ergonomics
Susin provides a variety of handwheel types — casting, fabricated, and chain wheels — scaled from 4 to 40 inches, ensuring that operators have ergonomic choices adapted to different torque requirements and operational contexts. Visible indicators on handwheels aid real-time valve status checks.

Installation and Mounting Interfaces
The actuators conform to ISO 5211 standards for flange mounting with detailed flange, bolt circle diameter (PCD), and dimensional data ensuring compatibility with global valve equipment. Detailed exploded views and parts listing enhance maintenance capabilities and spare parts understanding.

Global Partners and Facilities
SUSIN collaborates with partners in South Korea (I-TORK CONTROLS LTD), Germany (KTC SYSTEMTECHNIK GmbH), Malaysia, Singapore, UAE, Qatar, and Australia, maintaining manufacturing and assembly centers aimed at rapid local and international delivery. This integrated network strengthens supply chain resilience and customer support responsiveness.

Use Case and Operational Guidance
The included torque charts assist engineers in selecting appropriate handwheel sizes and torque outputs, factoring in the maximum allowable rim effort for user ergonomics. This practical tool supports optimized system designs that balance effort, safety, and control precision.
