Valve specifications usually start with size, flow rate, pressure rating, and chemical compatibility. Those factors matter, but they skip a question that shows up later in the build: Does the operator have valve handle clearance to actually reach and move it once the valve is bolted into place? A valve that checks every box on paper can still create a headache the moment it meets tanks, frames, plumbing, and guards.
Banjo gives designers options for working around tight spaces. Depending on the valve and application, designers can use a standard configuration without a riser, select a valve available with a riser already installed, or purchase a compatible riser kit separately. That flexibility can help resolve handle clearance challenges without redesigning the surrounding equipment.
A handle needs room to move through its full range, and the operator needs practical access once everything is assembled. Interference tends to show up in the same handful of places:
• Tank walls
• Structural frame members
• Adjacent plumbing
• Pumps and other components
• Guards and enclosures
• A neighboring valve or fitting
When a handle can't clear its surroundings, designers end up repositioning other components or reworking part of the layout just to accommodate a valve that should have been the easy part of the job. For OEMs working within a fixed equipment envelope, even a small clearance conflict can ripple into a larger redesign.
Rather than adding accessories unnecessarily, start with the clearance the application requires. If the standard configuration provides unobstructed handle travel and practical operator access, no riser is needed. When additional clearance is required, some valves can be ordered with a riser installed, or a compatible riser kit can be purchased separately. Either approach gives designers additional handle clearance while keeping the choice focused on the application.
This flexible engineering philosophy extends across Banjo's product line, including manifold flange connections designed to streamline assembly from the start.
Start by checking the handle's full travel and the operator's access in the assembled equipment. If surrounding components interfere, a riser can provide additional clearance between the handle and valve body. The choice is whether a riser is needed and, if so, how to obtain it.

Configuration / Option |
Primary Function & Fit |
Ideal Application Scenarios |
|
Standard configuration, without a riser |
Keeps the handle in its standard position relative to the valve body. |
The handle clears surrounding components and is easy to reach and operate. |
|
Valve ordered with a riser installed, where available
|
Provides additional handle clearance through a riser supplied with the valve. |
The equipment design requires a riser and that valve configuration is available to order. |
|
Riser kit purchased separately |
Provides the same clearance function using a separately purchased kit for a compatible valve.
|
A riser is needed but is not being supplied installed on the valve. |
Sometimes the valve body fits the installation, but the handle cannot clear nearby plumbing, frame members, or other components. A separately purchased riser kit provides the same clearance function as a riser supplied installed on the valve. Catalog listings may refer to these accessories as "handle offsets."
Compatible riser kits can also be stacked when additional clearance is needed. Work with Banjo to confirm the appropriate valve, kit, and installation arrangement for the application.
Whether the riser is supplied, installed or purchased separately, the goal is the same: provide room for handle travel and practical operator access within the equipment layout.
OEMs rarely design around a single valve. Moving a tank, pump, or frame member just to clear a handle causes expensive ripple effects. A modular handle system can:
• Help fit tight equipment envelopes and reduce layout changes
• Reduce the risk of prototype-stage handle interference
• Support practical operator access
• Support use of a common valve platform across models, where requirements allow
Answering a few key questions up front saves major rework down the line:
• Clearance: How much space exists around the valve?
• Interference: What might block travel once assembled?
• Accessibility: Can operators reach it easily and consistently?
• Riser requirement: Does the standard configuration provide enough clearance for full handle travel and operator access?
• Configuration and fit: Is the valve available with a riser installed, or is a separate compatible kit needed? If stacking is being considered, has Banjo confirmed the arrangement?
Catching conflicts before build time is the difference between smooth assembly and late-stage headaches. Banjo's experts can guide your choice, supported by a full product catalog built for versatile design.
Handle placement seems minor until it stops production. Banjo's flexible handle system gives you smart options to solve tight-space challenges, backed by the original yellow handle standard OEMs trust.
