Features & Benefits Low hysteresis across the operating range, achieved by the new compact design, providing accurate flow control.

Accurate activation values give peace of mind when calculating system pressure loss.

Excellent performance coverage from the DN32 ensures smaller pipework can be specified, compared to using larger sized valves. A real saving for the contractor & end user.

Reductions in weight and footprint allow the valves to be used within smaller voids.

VARIABLE FLOW

Pressure Independent Control Valve In modern Building Services projects, the desire for energy efficiency is a primary consideration for designers, installers, manufacturers, and end users. HVAC systems offer an excellent opportunity for energy savings if the correct products are specified, selected and installed and the use of these products is clearly understood. For installations incorporating items such as fan coil units (FCU) or chilled beams, the Hattersley PICV offers an excellent solution for control of water flow rates, and therefore comfort control and energy savings when used as part of a variable volume system design. For the installer, we offer a range of solutions which are easy to select, install and commission. Developed in the UK, tested to BSRIA PICV standards and utilising highquality materials, these valves can provide equal percentage performance which delivers optimum control valve authority. Hattersley go further to give you the flexibility, offering various actuator options and measuring points, along with a wide differential pressure and flow rate range available. All these factors combine to ensure our product will help you to design, deliver and maintain a system, which closes the performance gap and enables energy and cost reduction over its lifetime.

Control Characteristics The Fig. 1934 Elite Prime PICV is designed with a linear control characteristic to ensure good control over the flow rate at all settings. Our intelligent actuator controls the linear valve characteristics to an equal percentage characteristic at all valve settings.

VARIABLE FLOW

How Does the Hattersley PICV Work? 1. Differential Pressure Control As the flow rates in the distribution pipework fluctuate to match demand, the available pressure at individual terminal units varies. This variation in available pressure has the effect of changing the flow rate through the terminal sub-circuit, i.e. an increase in pressure gives an increased flow rate.

DIFFERENTIAL PRESSURE CONTROLLER

P1 P2

To negate these fluctuating pressures, the PICV maintains a constant pressure drop across its seat P1 to P2, therefore maintaining a constant flow rate to the terminal.

2. Flow Regulation By changing the open space, through which the water flows within the valve, the flow rate can be adjusted and set. The pressure across the seat of the PICV is held constant by the differential pressure controller. Whilst setting, the open area around the disk will change, resulting in a change to the flow rate. The new set flow rate recreates the constant seat differential pressure P1 to P2. Having set a new flow rate, it will stay constant at the new set value.

CHANGE IN OPEN AREA FOR FLOW OF WATER

3. Comfort Control The use of a PICV, as with all 2 port control valves, allows for the variation of the flow rate to vary the heat output of the terminal unit. The PICV is an integral part of the control loop.

FAN COIL UNIT

4. Thermostat, BMS, PICV & Terminal Unit By varying the flow rate we can control the heat output of the terminal. For PICVs with an equal percentage characteristic, there is a direct relationship between valve position and heat output, i.e. half open = half heat output.

VARIABLE FLOW

Actuator Options Electro-Mechanical Actuators – Modulating Forced convection (active) terminal units, i.e. FCU (Fan Coil Units) and active Chilled Beams are designed to be very responsive to changes in room temperature. Modulating actuators enable flow rate changes, and consequently heat output changes, to quickly match demand requirements, therefore, modulating actuators should be chosen for forced convection terminal units. Modulating actuators allow all intermediate flow rates between full flow and no flow.

Fail Safe ACT1934FS is a Fail Safe actuator designed to protect the equipment and the system from damage, while enhancing overall efficiency. In the event of a disruption to the power supply the actuator will drive either open or closed, powered by an internal super capacitor. The failsafe actuator can be fully configured using the user-friendly configuration tool (available separately). Failsafe models include 0-10V positional feedback signal function.

Feedback ACT1934FB is a Feedback actuator allowing modulating control with 0-10V positional feedback signal function. The feedback signal can be used by an external monitoring system to compare with control signal in order to check for ensure system is functioning correctly.

This now includes a stem gap detection innovation, which reduces onsite adjustments and results in easier installation and commissioning. The gap detection feature matches the stroke length of the valve during calibration, ensuring the actuator conversion to equal percentage is accurate and gives the desired flow control across all valve settings for the operating differential pressure range. • ACT1934FB is a Feedback actuator allowing proportional control with 0-10V with position feedback signal function. • ACT1934FS is a Fail Safe actuator Designed to protect the equipment and the system from damage, while enhancing overall efficiency

The origins of Hattersley date to 1897, when 20-year-old Richard Hattersley started a small tool-making business in Halifax. Today the portfolio of products and solutions has grown considerably and Hattersley is now a leading manufacturer of HVAC valves. The new Elite Prime PICV range is manufactured in Great Britain – designed and developed in Ipswich and manufactured in dedicated facilities in Hitchin using high-quality precision-made DZR components.

5 Step Process to Ensure Top Quality The new Elite Prime undergoes a 5 key step process for the manufacturing build and each valve is tested in accordance with BSRIA BTS01 guidance. 1. Assembly of shell & bonnet 2. Assembly of diaphragm 3. Assembly of top valve works 4. Furness Controls Pressure Test 5. Curtis Assemble and Test

In step 4, the Furness Controls Pressure Test is looking for any leakages utilizing a pneumatic pressure decay system. All the valves are individually pressure tested to BS EN 12266-1. Finally, in step 5, the PICV must undergo flow testing on a specially designed Curtis assembly & test performance rig. In the case of the Elite Prime PICV DN15 standard model, there are 14 key criteria in total which must all be passed. These tests cover verification of flow performance across differential pressure range and hysteresis check.

Practical Training At Hattersley we offer fantastic practical training in the form of a live demonstration rig. These training programmes are run by our Technical Sales Manager. Often run alongside our CPD training programme these sessions are a great way for us to offer hands-on training. • Accredited by CIBSE • Available at customer’s premises or hosted at Hattersley facilities • Training day available with chosen CPD, demonstration rig and factory tour

At Hattersley we are pleased to offer an opportunity to visit our manufacturing site, based in Hitchin, Herefordshire, to view first-hand how these valves are manufactured and tested in accordance to the latest standards and professional body guidelines (e.g. BSI, BSRIA, CIBSE etc.). A day can be organised to the customers’ bespoke requirements, combing your chosen CPD session with practical experience using the training rig and a factory tour.
