OPTIMA Compact HCR

Pressure independent control valve

OPTIMA Compact HCR pressure independent balancing & control valves (PIBCV) are used in Industrial applications for heating & cooling of processes and process control.

OPTIMA Compact HCR provides modulating control with full authority regardless of any fluctuations in the differential pressure of the system.

OPTIMA Compact HCR combines an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve.

OPTIMA Compact HCR makes it simple to achieve precise control of the water flow in the system, supporting stable operation and potential energy-efficient performance.

An additional benefit is that no balancing is required if further stages are added to the system, or if the dimensioned capacity is changed.

Potential energy savings through improved control, lower flow and reduced pump pressure. Improved Δ

Benefits

Design

• Less time to define the necessary equipment for ahydraulic balanced system (only flow data are required)
• No need to calculate valve authority. Valve authority is maintained at 1 by design.
• Flexibility if the system is modified after the initial installation

Installation

• No further regulating valves required in the distribution pipework when OPTIMA Compact HCR is installed at the terminals.
• Total number of valves minimized due to the 3-in-1 design
• Minimized commissioning time due to automatic balancing of the system
• No minimum straight pipe lengths required before or after the valve.

Operation

• Supports occupant comfort through high precision temperature control.
• Longer life due to less movements of the actuator

Features

• The presetting function has no impact on the stroke; Full stroke modulation at all times, regardless the preset flow.
• The constant differential pressure across the modulating control component is designed to maintain full valve authority.
• Automatic balancing is designed to prevent overflows under varying pressure conditions in the system.
• Motoric actuator 0-10 V, 4-20 mA and 3 point control
• Differential pressure operating range up to 600 kPa
• High flows with minimal required differential pressure due to advanced design of the valve
• Small dimensions due to compact housing
• Pressure class PN16/25/40 in same housing
• Higher presetting precision due to stepless analogue scale
• Rangeabililty > 100:1
