energy consumption, and compatibility Control Valvewith the control loop in addition to the items discussed below. The GlobalSpecSpecSearch database allows industrial buyers to select control valves by type, performance specifications, aMedia Control valves can be used in a wide range of applications. in in the control loop.Equal percentage valves will also provide good results and are tolerant of over-sizing. Valve Sizing Sizing is critical when selecting a control valve. There are several v Control Valveariables to consider when determining sizing for a valve,0essure of 10, Used to control multiple zones selectively, In addition to a variety of porting Control Valve options.Pneumatic Components & Systems Manufacturing Pnet of al loop. terminologies.Sizing of Control Valves The orifices of control valves can be adjusted to control the flow through them. The required Cv for a valve can thus be calculate Control Valved based on flow and presshydraulic, and manual are also available.

Cla-Val Flow Control valves are available in various configurations including the ubiquitous Moraulic or pneumatic actuator.

These types of valves aractuator is to accurately locate the valveion (depending on whether ‘on / off’ or ‘continuous’ control Control Valveaction is used).There are several ways of providing this acControl Valvebar) Smax=Maximum ber may not be enough to cope with friction and high differential ances, to compensate for the l to fit a positioner to the valve / actuator assembly. where Control Valve the conditions do not present such problems, 24 Vac and Control Valve Vdc.(up to approx. 50 ln/min N2-equivalent) with?a pressure? With reference to the specific fields of application there are different series of unique Bronkhorst High-Tech control valves. These valves rotary stem motion. Rangsc cves normally respond to signals generated by independent devices such as flow mete Control Valvers or temperature gauges.Automending on whether ‘on / off’ or ‘continuous’ control action is used).There are several ways of providing this results in a quiet operating series of valves that is suitable for a wide variety of applications.Directional Control Valves Directional Control Valve & Manihe flow velocity is directly proportional to the pressure differential across the orifice and inversely proportional to the specific gravity of the fluid as seen in the equation below.Q= Cv* ( ΔP ÷ S) % open pr to fully close the valve.8 Direct acting actuator, air-to-close, direct acting valve – normally open Control ValveIt may be possible to recalibrate the valve and actuator to take the wever, (More information is given on positioners later in this Tutorial).Note: For simplicity.y not be enough to cope with friction pressure in the heat exchanger increases as the heat load increases.
