Poor resistance to Ketone's and Acetone.

HNBR

HNBR (Hydrogenated Nitrile Butadine Rubber) also known as Therban, Zetpol or Tornac). Good for motor oils, sour gas, amine oil mixtures, oxidised fuels, lubricating oils, mineral based hydraulic oil, animal and vegetable oil, diesel fuel, ozone, dilute acids and bases, new bio-oils, H2S Hydrogen Sulphide and C02 carbon dioxide. -40°C to +150°C. Poor for concentrated alkali's, esters, alkyl phosphate, ethers, halogenated solvents, ketone's, halogenated hydrocarbons, solvents and flames.

Hypalon

Hypalon is a chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM). Good for chemicals, ozone, ultraviolet light, oxidising agents, hot water, corrosive chemicals, low gas permeability, good electrical properties, low flammability. -35°C to +125°C. Poor to fair fuel resistance and its low temperature properties are generally limited.

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.

Neoprene

Neoprene known as CR or Chloroprene. Good resistance to Freon and ammonia, flames, excellent UV resistance, Ozone, oxygen and sunlight, tough, abrasion resistant and has a low compression set with an outstanding ability to adhere to metals. -20°C to +110°C.

Silicone

Silicone (VMQ) known as PVMQ, Silastic, Siloprene, Rhodorsil or Silplus. Good resistance to Oil, solvents, aniline alcohol, dilute acids or bases, benzene, toluene, petrol. -60°C to +230°C. Poor resistance Diesel, hot air, steam over 150 C, strong acids and bases.

VST

VST (Viton-Silicone-Teflon). Has enhanced chemical resistance compared to Viton, especially against aggressive chemicals like ketones, esters, and some organic acids. Combines the properties of Viton, silicone, and Teflon, offering improved flexibility, compression set resistance, and low-temperature performance compared to standard Viton. -40°C to 200°C

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.

Voltage

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.

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.

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.
