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.

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.

PTFE (Teflon)

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

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.

Degreased

Oil and grease removed typically for oxygen or paint spray use.

Manual Override

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

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.

Shading Ring - Silver

The copper shading ring in the solenoid tube has been replaced with silver. Typically used for RO water and aggressive media applications.

Shading Ring - without

The copper shading ring in the solenoid tube has been removed, for DC voltages only and typically for aggressive media applications.
