Industrial Control Valves — Manufacturer, Supplier & Stockist
Control valves automatically regulate flow, pressure, temperature or liquid level by varying the size of the flow passage in response to a signal from a controller. Navjivan Valves supplies pneumatically actuated control valves across globe, butterfly and ball-type control valve bodies for process automation applications.
Product Overview
Where an on/off isolation valve simply stops or starts flow, a control valve modulates continuously between open and closed to hold a process variable — flow, pressure, temperature or level — at a required setpoint. Selecting the right control valve involves matching the valve type, size, pressure and temperature rating, and flow characteristic (linear, equal-percentage or quick-opening) to the specific process duty.
Types of Control Valves
Globe-Body Control Valves
The most common control valve body style, offering good throttling characteristics and a wide range of trim options for demanding process duty.
Butterfly-Type Control Valves
A compact, lightweight option for larger line sizes and lower pressure-drop applications, particularly in water and HVAC systems.
Ball-Type Control Valves
Offer high capacity in a compact envelope and are well suited to applications with entrained solids or where tight shut-off combined with control is required.
