Valves & Controls

Somewhere on almost every process line there's a point where flow has to start, stop, throttle back, or divert — and it's a valve, an actuator, or a regulator doing the actual work, usually specified well after the pumps and instrumentation. Z & F Corporation Ltd supplies genuine valves, actuators, and regulators across 849 lines from 25 manufacturers, covering everything from a manual ball valve to a fully positioned control valve assembly. This category is a hub over three more specific ranges — browse directly if you already know what you need: Industrial Valves — ball, plug, gate, globe and control valves in a range of body materials and end connections. Actuators & Positioners — pneumatic and electric actuators, rotary and linear, plus digital and pneumatic positioners. Pressure Regulators — reducing and back-pressure regulators for gas and liquid service. For the instrumentation that monitors what these are doing, see Instrumentation — this range covers the equipment that acts on the process rather than measures it. Actuation itself splits fairly cleanly into a few families: simple on/off pneumatic or electric actuators for isolation duty, modulating actuators taking a 4-20mA or 3-15psi control signal for throttling service, and digital positioners that convert a control signal into precise valve travel with local feedback. Which one you need usually comes down to the control loop it sits in, not the valve itself.

Obsolete Actuators & Superseded Valve Models A lot of the valve and actuator enquiries we get are for models the manufacturer has since superseded or discontinued. We source through multiple channels and can often find remaining genuine stock or confirm a direct replacement, including for actuators still running on older plant. Orders ship worldwide with export documentation as standard — recent shipments have gone to buyers across the GCC, East Africa, and South Asia, alongside our UK and European base. If you're specifying against a datasheet, send us the model number or the full spec and we'll confirm stock, pricing, and lead time.
