The best spring brake control valve depends on your vehicle’s original part number, port layout, and air-brake plumbing. The 110800 is a strong match when its four-port specifications and cross-reference numbers fit; the World American WA110500 is better for buyers replacing a 110500-style valve; and the Torque 110170 suits applications requiring its listed dual parking and emergency brake functions. Confirm the part number and port configuration before ordering.

110700 Spring Brake Control Valve
This listing is best for buyers who have identified a failed 110700 valve and need a replacement bearing that part number. The product name describes it as compatible with Sealco and lists 3/8-inch and 1/2-inch NPT sizing. That makes it important to compare the existing valve’s markings and threaded port sizes before purchase.
Why it was selected: It directly matches the requested 110700 spring brake control valve category. Limitation: The provided listing information does not specify the number or function of each port, so verify the valve diagram and plumbing requirements before choosing it.
110500 Spring Brake Valve, Two-Piece Listing
This 110500 valve is best for buyers whose existing equipment calls for a Sealco 110500-style spring brake valve. The listing describes a 3/8-inch port and a zinc-alloy construction. It also states that the valve is pneumatically and submersion tested for leakage, and describes the design as intended to support air flow and responsive braking.
Why it was selected: Its 110500 designation and stated port size give buyers useful replacement details. Limitation: The title says “2 pcs,” but the supplied description does not explain what the two pieces include. Confirm package contents and all port specifications before ordering.
110800 Spring Brake Control Valve
The 110800 is best for buyers whose part number or cross-reference matches the listing. It gives a detailed four-port specification: 3/8-inch NPT supply and control ports, a 1/2-inch NPT reservoir port, and a 3/8-inch NPT delivery port. The stated trip pressure is approximately 80 PSI.
Why it was selected: Its port details and extensive listed cross-reference numbers make it easier to compare against an existing valve. The listing also describes zinc-alloy construction and pneumatic and submersion testing. Limitation: The trip pressure is approximate; confirm that the valve’s specifications match the vehicle’s requirements.
World American WA110500 Spring Brake Valve
This valve is best for heavy-duty truck or trailer owners replacing a 110500-style spring brake priority valve. The listing identifies it as a replacement for several part numbers, including Sealco 110500, Meritor RSL110500, and Bendix K025778. Its configuration includes 3/8-inch supply and control ports, two 3/8-inch delivery ports, and a 1/2-inch reservoir port, all with NPT threads.
Why it was selected: The stated replacement numbers and port layout support a direct comparison with an installed valve. Limitation: Do not rely on the general heavy-duty application description alone; check the exact part number and port arrangement.
Torque 110170 Spring Brake Control Valve
The Torque 110170 is best for buyers matching a 110170 application who need a valve listed for both parking and emergency brake functions. Its described layout has a 3/8-inch supply port, four 3/8-inch delivery ports, two 1/2-inch reservoir ports, and a 3/8-inch control port.
Why it was selected: The listing names replacement references including Sealco 110170 and Meritor RSL110170, alongside its port configuration. Limitation: This layout differs from the other valves here; avoid choosing it based only on the general term “spring brake valve.” Confirm the matching part number and plumbing.
Buying Guide
How do you match a replacement valve?
Start with the number stamped on the old valve or the vehicle’s parts documentation. Compare that number with the replacement’s listed cross-references. Similar names do not guarantee that two valves share the same functions or connections.
Why do port sizes and positions matter?
Check each port’s size, thread type, and purpose, including supply, control, delivery, and reservoir connections. A valve with the wrong port arrangement may not match the existing air-brake plumbing. Use the product specifications and vehicle service information rather than assuming that similar NPT sizes mean the valves are interchangeable.
What else should buyers verify?
Confirm the application with a qualified parts supplier or technician when the original part number is unclear. For a safety-critical air-brake system, installation and inspection should follow vehicle manufacturer guidance. Product descriptions alone cannot confirm that a valve is correct for every truck or trailer.
Frequently Asked Questions
What does a spring brake control valve do?
It controls air pressure related to spring brake operation. The listed Torque 110170 product specifically describes control of parking and emergency brake functions.
Can I replace one valve with another that has similar port sizes?
Not necessarily. Match the part number, port functions, and layout as well as the thread sizes.
What does NPT mean in a valve listing?
NPT identifies the listed pipe-thread type. Check that the replacement’s thread size and port purpose match the original installation.
Which product has the most detailed port information?
The 110800 listing specifies supply, control, reservoir, and delivery port sizes, as well as an approximate trip pressure.
Should I install a spring brake valve myself?
Use vehicle service guidance and appropriate expertise. If you are unsure about air-brake components or connections, consult a qualified technician.
