FLOW CONTROL PRODUCTS

Pennant Control Valve-Pcv

Pennant offers the top – guided globe valve to meet a wide range of automated process control applications. The product features a single – ported design configuration, which permits numerous trims, actuation and instrumentation solutions. Rugged top – guiding of the plug ensures maximum valve stability under the most adverse conditions.

Features of Pennant control valve

  1. High Flow Capacity
  2. Excellent Flow Control Range ability
  3. Tight Shutoff
  4. Pennant control valves are designed and tested to deliver 100% performance under specified operating conditions.

Characteristics and Types

The different types of control valves are classified by a relationship between the valve stem position and the flow rate through the valve. This control valve characteristic is assigned with the assumptions that the stem position indicates the extent of the valve opening and that the pressure difference is determined by the valve alone. There are three basic types of control valves.

  1. Quick Opening – For frequent on-off services. Process where instantly large flow is needed like safety systems or cooling systems.
  2. Linear – Typically used for level control or flow loops, in steady state systems where pressure drop across the valve is expected to remain fairly constant.
  3. Equal Percentage – Typically used for pressure, temp., flow control used where large changes in pressure drop across the valve is expected. Used in temperature and pressure control loops.
