Valve / Product Type

Air Actuated Valve

air actuated valves that utilise a compressed air supply to operate.

Ball Valve

Motor and air actuated quarter turn 2+3 way ball valves

Condensate drain

Automated + time control drain valves

Motor Actuated Valves

Proportional Modulating

Flow regulating valves with manual or electric modulating 4-20mA control.

Safety Shut Off

Safety shut off isolation valve, shuts off and secures air line systems, will vent downstream air when closed.

Timed control

Time control valves can be set to activate according to preset intervals when power is applied.

Function

2/2 Normally Closed

2 ports (inlet/outlet) with 2 positions (Open/Closed) - valve stays closed (Failsafe) requires power to open

2/2 Normally Open

2 ports (inlet/outlet) with 2 positions (Open/Closed) - valve stays open (Failsafe) requires power to close

2/2 Latching

2 ports (inlet/outlet) with 2 positions (Open/Closed) - short power pulse valve stays open - reverse power pulse valve stays closed

2/2 Double Acting

2 ports (inlet/outlet) with 2 positions (Open/Closed) - power or air one side to move - power or air opposite side to return.

3 way T Port

3 way L Port

Power Open/Power Close

Valve requires power to open and power to close, no power valves stays in position.

Proportional / Modulating

Valve opens proportionally according to signal input, either 4-20mA, 0-10v or 0-5 volt. Example 4mA valve closed, 8mA 25% open, 12mA 50% open, 18mA 75% open and 20mA fully open.

Pressure

Seals

EPDM

EPDM (Ethylene Propylene Diene Monomer) - known as Ethylene Propylene terpolymer, Buna-AP, Dutral, Polysar-EDM, Royalene, Vistalon, Keltan, Epcar, Nordel or Epsyn). Good for hot and drinking water, Steam, Freon refrigerant gas and Air -40°C to +120°C (+150°C steam) Poor resistance to oils + fuels

FKM (Viton)

FKM Fluoro elastomer (Fluorocarbon) Viton® Dupont registered, known as Tecnoflon, Fluorel, Dai-El. Good for hot water, acid, alkali, oils, hydrocarbons and salt solutions, many aggressive chemicals, diluted acids, weak alkali's, mineral oils, aliphatic and aromatic hydrocarbons, chlorinated hydrocarbons, sunlight and ozone. -26°C to +205°C. Poor resistance to Ketone's and Acetone.

PTFE (Teflon)

PTFE (Polytetrafluoroethylene) also known as Teflon® Dupont registered. Excellent resistance to almost every fluid or gas. -200°C to +230°C

WRAS

WRAS approval ensures water fittings meet UK water regulations, safeguarding public health by preventing contamination, waste, and misuse of water supplies.

Orifice

Options required

Anti Water Hammer

Prevents or reduces water hammer caused by sudden changes in fast moving fluid flow.

Bi-Directional Flow

Can control flow in both directions

Flow Control

Flow regulation to control the amount of flow.

Manual Override

A facility to manually move the valve into the fully actuated position via a button, lever or key.

Mounting Holes

Supplied with additional threaded holes typically in the base, typically for securing to a baseplate.

Outlet - right angle

The outlet port is at right angles to inlet port, ideal for space efficiency.

Position Feedback Closed

The valve is equipped with an additional volt free electrical switch that is triggered when the valve is mechanically closed.

Position Feedback Open+Closed

The valve is equipped with two additional volt free electrical switches that are triggered when the valve is mechanically closed or open position.

Position indication Visual

The valve is equipped with clear cover or dome under which an arrow or flag can be seen to confirm either the open and or closed position of the valve.
