Valve / Product Type

Coaxial Valve

Filters Regulators & Oilers

Air pressure regulator with air filter with air lubrication system. Provides stable outlet pressure whilst removing debris and 90% moisture the finally providing oil mist to lubricate downstream equipment.

Manual + Mechanical Control

Air valves that are controlled manually and mechanically

Pressure Switch / Transmitter

Pressure switches and pressure transmitters

Pressure Reducing

Pressure reducing valves (PRV) reduce and maintain stable outlet pressure

Pressure Relief

Safety pressure relief / pressure limiting valve (PLV), stays closed until pressure reaches set pressure - then quickly opens, releasing any excess pressure.

Pressure Sustaining

Pressure sustaining / back pressure valve, maintains a minimum preset upstream (Inlet) pressure, valve will close if pressure drops to set pressure and reopens when inlet pressure increases again.

Proportional Modulating

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

Solenoid Valve

Valves controlled by electrical signal via a solenoid or electro magnet.

Function

2/2 Failsafe Closed

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

2/2 Failsafe Open

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

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.

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.

NBR

NBR (Nitrile Buna Rubber) known as Nitrile Butadine, Buna-N, Hycar, Chemigum, Butakon, Breaon, Butacril, Paracil, Nipol, Perbunan, Krynac or Europrene-N. Good for Aliphatic Hydrocarbons, Petroleum, Fuels, Mineral Oil, Vegetable and Hydraulic Oil, Alcohol and many Acids. -35°C to +100°C. Poor for Ozone, Acetone, Methyl ethyl Ketone, Chlorinated Hydrocarbons, Ethers and Esters.

Approval: ATEX,WRAS,IP etc

ATEX ExnA

certifies equipment for use in potentially explosive atmospheres, indicating it is designed to prevent ignition sources, minimizing risk.

IP65

Dust tight and protected against water jets

IP66

Dust protected and protected against powerful water jets.

Orifice

Operation

Direct Acting

Directly controls flow without external pressure assistance operates from vacuum upwards.

Pressure Assisted

Operate via pilot pressure control and require a minimum pressure difference between inlet and outlet from 0.5 Bar.

Options required

Anti Water Hammer

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

Flow Control

Flow regulation to control the amount of flow.

Manual Control

Valves that require manual input to operate such as lever, button or switch

Manual Override

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

Mounting Bracket

Valve has the facility to be supplied with a bracket for mounting and securing.

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.
