644 Fisher Actuator
KKM Solutions is an independent parts distributor, not an authorized Fisher dealer — how we source.
Overview
Part number 644 from Fisher, listed in Valves & Process Control. KKM Solutions quotes this part with pricing and availability confirmed per order.
Fisher 644 and 645 actuators are used to automatically control steam-driven boiler feedwater pumps (reciprocating or turbine). The 644 or 645 actuator, when used in combination with one of several push-down-to-close sliding-stem valves, forms a pump governor. 644 and 645 actuators may also be combined with push-down-to-open valves to be used as relief governors.

Frequently Asked Questions
How do I get pricing for 644?
This part is quoted on request, so no price is listed for it here. Send the quote form on this page with your quantity, or email orderdesk@kkmsolutions.com, and our order desk will reply with pricing and availability within 1 business day.
Who manufactures the 644?
644 is made by Fisher and is listed in our Valves & Process Control category. KKM Solutions is an independent distributor, not an authorized Fisher dealer: we source the exact Fisher part number 644, and the quote confirms condition and lead time before you order.
Is the 644 new and genuine?
Parts we supply are new and genuine unless the quote expressly states otherwise. Where a part is new-old-stock, from excess inventory, refurbished or open-box, the quote says so before you approve it.
What warranty comes with the 644, and can I return it?
Parts we supply are warranted against manufacturing defects for 1 year from the date of delivery; where the manufacturer's own warranty is longer, the manufacturer's warranty applies. The warranty covers repair, replacement, or credit of the defective part and does not cover normal wear items, misapplication, improper installation, or consequential damages. Contact us within 30 days of delivery before returning anything — all returns need a return authorization from the order desk.
What is the lifecycle status of 644?
No published lifecycle status is on file for 644. Fisher lists whether a catalog number is current, superseded or end-of-life on its own product page, and our order desk confirms the status with the manufacturer at quote time, before you commit. Send the part number through the quote form on this page.
How quickly can 644 ship?
Lead time for 644 is quoted per order and confirmed on your quote, which our order desk sends within 1 business day. For a line-down emergency, call the 24/7 order desk at (825) 454-5367.
