The Engineered Solutions Process

With years of experience as a custom valve manufacturer, we have perfected the Humphrey Engineered Solutions development process. While we do the heavy lifting, you will collaborate and consult with Humphrey engineers throughout development. Here's how:


A series of visits and/or phone calls to capture enough technical, commercial and schedule (timeline) requirements for the project.

Includes identifying any quality and regulatory requirements, and post-sale support expectations.

An initial project proposal (SOW), summarizing details and estimated budget, is prepared for review and approval by the client.

Sketches and drawings are prepared (at times more than one possible solution) and until a design is agreed upon for prototyping.

It is possible multiple prototype loops are necessary until a final working prototype is approved.

Phase ends with a customer specification drawing produced and agreed upon, capturing all technical, quality and performance attributes of the product.


A formal proposal is prepared to an appropriate detail such that a purchase order or contract can be issued by the client.

Once received, production readiness activities are executed, including tooling and fixtures, assembly and test equipment, and part qualification submittals.

Often, a pre-production qualification cycle is scheduled and completed.



Production begins with the end in mind – to ship defect-free, on-time and as-promised to customer satisfaction.

Follow up visits are common, particularly meetings with those who live with the product after the development period (i.e., your quality and production staff).

We seek long-term, mutually beneficial relationships, earned through trust via excellent performance and service.
