rotary control valves

Rotary control valves are a class of control valves that use a rotating motion to regulate flow. Known for their compact design, high flow capacity, and excellent control performance, these valves are widely used in applications where space is limited, fast response is required, or media conditions are harsh.

As a dedicated reseller and distributor of globally recognized valve manufacturers, Petromarsh provides industry-proven rotary control valves tailored for demanding service across the energy, process, water, and manufacturing sectors.

🔍 What Are Rotary Control Valves?

Unlike globe or linear valves, rotary control valves regulate flow by rotating a plug, disk, or ball within the flow path. This rotary motion allows for:

• Compact valve body design

• Faster actuation

• Reduced wear and maintenance

• High flow capacity (Cv) per size
  
  

These valves are ideal for continuous modulation, on-off service, or where tight shutoff and low torque are essential.

🧰 Rotary Valve Types We Supply

As an authorized distributor, Petromarsh offers a wide selection of rotary control valve types, including:

• Segmented Ball Valves (V-Port)
  Ideal for precise control in slurry, pulp, or high-viscosity services. The V-notch ball design delivers linear or equal percentage flow characteristics.

• High-Performance Butterfly Valves
  Torque-seated valves that offer reliable shutoff and modulating control in high-pressure and high-temperature systems.

• Eccentric Plug Valves
  Suitable for throttling abrasive or slurry flows with minimal seat wear due to their cam-action closure.

• Triple Offset Valves (TOV)
  Combines zero-leakage shutoff with rotary modulation, often used as control valves in critical gas and steam applications.

• Rotary Globe Hybrid Valves
  Advanced designs combining globe-like accuracy with rotary efficiency for compact modulating solutions.
