Description

The FK Series Polypropylene Butterfly Valves incorporate many features of our industrial FK valve, yet the all Polypropylene construction and EPDM liner make this valve the perfect choice for water and light industrial applications. The special trapezoid shape of the liner and serrated body cavity guarantee a bubble tight seal while keeping break-away torque at an absolute minimum. This versatile valve features double self-lubricating seals, direct actuator mount capability, or the option of either a lever handle or gear box.

V4 Series - Low-cost industrial, epoxy coated aluminum, on/off or modulating

Datasheet Manual	Voltage
	120VAC
	24VDC
	12VDC
V4 Actuator Accessories 2 Extra Limit Switches 2 additional SPDT dry contact mechanical switches Modulating Positioner Positioner board allows for modulating control of the valve with either a 4-20mA or 0-10VDC control signal. If control signal is lost and main power is present, actuator will move the valve to the position corresponding to the low end of signal. Choose your control input signal: 4-20mA (4 = Closed, 20 = Open) 0-10VDC (0 = Closed, 10 = Open) Reverse control signal

	S4 Actuator Accessories Modulating Positioner The DPS is a digital positioning system that uses a microprocessor to modulate the actuator in proportion to an anolog input signal (4-20mADC or 0-10VDC). Choose your control input signal: 4-20mA (4 = Closed, 20 = Open) 0-10VDC (0 = Closed, 10 = Open) Reverse control signal Battery Fail Safe The BSR is a battery fail-safe module where an internal battery pack powers the actuator to the preset failure position "open or closed" upon loss of power. The BSR can be used with the DPS positioner. Choose the failure position: BSRC: fail CLOSED BSRO: fail OPEN Alternate DIN Connectors Actuator ships with Cord Grip (cable gland) DIN Connectors installed.These additional connectors will be included loose in shipment. Simple one screw changeout for each connector. Cord Grip (standard) 1/2" NPT Conduit Corded Choose the additional Connector Style: 1/2" NPT Conduit 15 foot Cord
