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

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 Maximum

Seals

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

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.

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.

Bi-Directional Flow

Can control flow in both directions

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 proximity switch - Open

The valve is equipped with an additional volt free electrical switch that is triggered as the valve reaches the 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.

Y Pattern

A Y-pattern valve is a valve with a Y-shaped body design, typically used for high-pressure applications to reduce pressure drop and turbulence, often found in steam systems.
