Actuated Valves

Introduction:Why to motorize a valve?

▪ Distant Location of the valves to be operated▪ Need to have information about position ofthe valve every time▪ Simultaneous functions: no possibility tooperate few valves at a same time▪ Reliability / Safety/ repetitive functions: toavoid possible human mistakes (someoneforgot to open/close the valve)▪ Avoiding forbidden operations▪ Positioning (modulation)▪ Comfort▪ High torque

Actuated Valves

Electric Actuation: introduction

▪ The electric actuator operates the valve through an engine switched on by electricsignals.▪ At the reception of the electrical signal the engine turns according to the signalreceived until the internal cam presses the corresponding microswitch. ▪ Once the following signal is received, the engine turns on the opposite direction.

Actuated Valves

Electric Actuation: J+J - Main features

▪ ATC TEMPERATURE THERMIC CONTROL: 4 W heater thermostatically controlled to maintain thetemperature inside between 20ºC & 30º (68º F – 86º F) and avoid failures caused by condensation.

Actuated Valves

Pneumatic Actuation: introduction

▪ The pneumatic actuator is based on a pinion-rack mechanism.

▪ Using compressed air that intakes/outlets the chambers of the actuator andpushes/operates a piston´s gear assembly which turns the central shaft and operatesthe valve.

▪ Two different versions: DOUBLE ACTING or SPRING RETURN.

Internal chamber

External chamber

20

Actuated Valves

Pneumatic actuation: double acting

▪ The double acting actuator works by means ofthe direct movement of the pistons. The airinjected in the actuator chamber puts certainpressure on the pistons, pushing them andoperating a rack system connected to the valveshaft.

▪ The use of a solenoid valve is needed. Thisvalve distributes compressed air in one or otherchamber, depending on ther is electric signal ornot.

▪ The speed of the opening or the closingoperation can be controlled through safetyregulators added to the solenoid valve. Strongly recommended in order to avoidwaterhammers or vibrations in the pipeline.

21

Actuated Valves

Pneumatic actuation: spring return

▪ The spring return actuator works through springssystem: when compressed air is injected in the internalactuator chamber at a certain pressure, the springs are retracted (making the valve open or close).▪ The lack of air in the chamber allows the springsexpansion (making the valve close or open).▪ The springs (by retraction or expansion) move a rack andpinion system connected to the shaft of the valve, so theball or disk opens or close.▪ The use of a solenoid valve is needed. The solenoidreceives information from the electric control box to allow ornot the continuity of the air-flow, activating or deactivatingthe valve operation.▪ It´s a safety device. In case of a temporary lack of airflow, the actuator goes back to initial position thanks to thesprings.▪ The spring return actuators are the solution for controlledemptying applications. For example, if we want to withdrawa fluid from a tank and we have a sudden lack of air flow orpower failure, the springs will return the valve to closeposition, avoiding an uncontrolled emptying.

22

Actuated Valves

Pneumatic Actuation: spring return vs. double acting

Spring Return (Air to Spring / Fail safe)

Requires air to open only, once air is exhausted springs closethe valve.

Fail position open or close if air supply is lost.

NC (fail safe close) o NA (fail safe open)

Double Acting (Air to Air)

Requires air to open and air to close.

No fail position if air supply is lost.

23

Actuated Valves

Electric Actuation vs. Pneumatic ActuationBenefits:

Comes with more serial components (limit-switches, manual control, etc.). No need for compressed aire installation (just electricity)Easy to installSpecially recommended when we need to actuate one or few valves.Modular systems. In case of requiring positioner, this will be installed internally (does not take extra-room)

Medium/high operation time (minimum 7-8 s), useful to avoid “water hammers”Possibility to add safety block (BSR) with battery for the maximum safetyConstant torque.Less weight / room.No minimum pressure required as with the solenoid valves (air).

Warnings:Not recommended for low time operation applications.Not recommended in explosion-risk environments, very humid or saline (ex: minery) Life: 20.000 cycles guaranteed.

ElectricActuation

31

Actuated Valves

Electric Actuation vs. Pneumatic Actuation

Benefits:Low operation time. In any case, the operation time can be regulated through escape regulators in the solenoid valve.Guarantees de maximum safety against supply failures (air and electricity) thanks to the spring-return.Appropriate for explosion-risk environments.Appropriate for installations with many actuated valves.1.000.000 cycles guaranteed. (appropriate for applications which require many operations daily).

WarningsWarnings::Requires compressed air supply as well as electricity supply to feed the solenoide valve.Not recommended for outsides (the compressed air can condensate) or when the valve is far-away (difficult to “send” the compressed air)Requires additional accessories: limit-switch box, solenoide valve, …The torque constant (and thus the valve operation time) depends on the air pressure and thus in the correct working of the compressed air installation (example: the closer valves have pressure, but not the distants ones)

IMPORTANT:

Always if possible is very important to have the maximum information about theapplication where the valve will be installed.

This way we can recommend better which actuator should be used.
