Two-Way ER Valves

These rotary valves have one inlet & one outlet. The valve can be either fully open to allow maximum flow, or fully closed. Both Normally Open (fail open) and Normally Closed (fail closed) configurations are available. The valves are designed to stop fluid flow in the direction of inlet to outlet only. The flow direction is shown by an embossed arrow on the valve body casting.

No differential pressure required to open. All valves operate from zero to maximum pressure listed in table.

Options

S - Single Switch - Indicates when valve is in its energized position. Specifications can be found here.

X - Single Switch Explosion Proof - Indicates when valve is in its energized position. Specifications can be found here.

M - Dual Switch - Indicates when valve is in both its energized and de-energized position. Specifications can be found here.

Y - Dual Switch Explosion Proof - Indicates when valve is in both is energized and de-energized position. Specifications can be found here.

L - Locking Manual Override - Mechanically locks the valve in its energized position.

T- Terminal Box - Enclosure with the terminal strip attached to the coil. Customer is responsible for creating cable entry into the enclosure.

H - High Temperature - For valves running fluid hotter than 350°F.

V- Vertical Pipe - Valve is able to be mounted for verticle flow instead of horizontal flow.

--Other Options--

ETL - Solenoid meets the requirements for use in Class I, Division I, Groups B-D hazardous locations. More information about the 400 and 800 Series solenoid ETL listed mark is available here.

OX - Valve is cleaned of all internal contaminants to allow use for oxygen service.

T5 - Valve is tested for Class V leakage per FCI 91-2-2004 with air.

HY - Valve is tested for Class V leakage per FCI 91-2-2004 with Helium. This is typically done for hydrogen service applications.

Two-Way ER Valves

Solenoid Actuated

Solenoid Actuated two-way ER valves will fully actuate between open & closed positions when power is supplied or lost. This allows these valves to be fully automated. For example, a Normally Closed ER valve will be fully closed when no power is supplied & fully open when power is supplied.


Solenoid Actuated
Action Actuates immediately when power is supplied, resets immediately on loss of power
Operation Normally Closed (energize to open)
Normally Open (energize to close)
Valves ER15 (Direct Operated Pilot Assisted) & ER16 (Direct Operated)

Emergency Trip

Emergency Trip valves are useful in applications requiring an emergency shutoff or dump. The valve actuates once, or 'trips', and remains in its tripped position until it is manually reset to its normal operating, or 'latched', position.



Trip When Energized
Latch Mechanical
Action Trips immediately when power is supplied
Reset Manual reset when power is off
Operation Latched Open, trips closed
Latched Closed, trips open
Valves ER17 (Direct Operated Pilot Assisted) & ER18 (Direct Operated)

Trip At Specified Temperature
Latch Mechanical
Action Trips when fusible link breaks at specified temperature
(135°F, 165°F, 212°F, 286°F or 386°F)
Reset Manual Reset, replacement of fusible link required

Latched Closed, trips open
Valves ER19 (Direct Operated Pilot Assisted) & ER20 (Direct Operated)

Trip On Loss Of Power
Latch Electromagnetic (power must be supplied)
Action Trips immediately on loss of power
Reset Manual reset when power is on
Operation Latched Open, trips closed
