Help Maintain Grip When Air Pressure Is Lost

A gripper holding a component should not become an afterthought when the compressed-air supply changes. The Röhm pressure safety valve is a pressure-maintenance accessory for compatible Röhm double-acting grippers, helping support the holding condition if supply pressure is interrupted. For replacement identification, Röhm 1078823 is the key manufacturer reference used across applicable RPP, RPP-A plus other compatible Röhm gripper configurations.

What Is A Röhm Pressure Safety Valve?

Small valve block. Very specific job.

Röhm identifies item 1078823 as a pressure-maintenance accessory for compatible double-acting grippers. Current manufacturer documentation shows it with four G1/8 connections plus port markings A1, A2, B1 & B2.

Within Röhm's documented RPP range, 1078823 is specified as pressure maintenance for RPP-50 through RPP-380. Röhm documentation also lists the same reference for applicable RPP-A configurations plus other compatible gripper families.

That makes the equipment relationship important:

compressed-air supply → control circuit → pressure safety valve → gripper → jaws → workpiece

The valve is therefore not simply another air fitting. It belongs to the pneumatic circuit responsible for maintaining the required state of the compatible gripper when supply conditions change.

Why Choose A Röhm Pressure Safety Valve?

Imagine a robot has already picked a component when the air supply is interrupted. The important question is no longer how quickly the jaws can move—it is what happens to the grip.

A pressure-maintenance valve addresses that part of the pneumatic system. On compatible double-acting Röhm grippers, it provides a dedicated solution for maintaining pressure rather than relying on an unrelated general-purpose fitting or an assumed substitute.

Identification is particularly straightforward when the original component, machine documentation or parts list shows 1078823.

Before selecting a replacement, establish:

► Röhm gripper family
► Exact model & size
► Existing valve item number
► A1, A2, B1 & B2 circuit routing
► G1/8 connection requirements where applicable
► Condition of the surrounding tubing & fittings
► Machine manufacturer's pneumatic circuit requirements

A matching thread is useful information. It is not enough on its own to establish the correct replacement.

Common Applications

RPP parallel grippers use pressure-maintenance valve 1078823 as a documented accessory across the RPP-50 to RPP-380 range.

RPP-A parallel grippers can use the same valve reference in applicable double-acting configurations.

Robotic handling cells may require pressure maintenance while a gripper is carrying, positioning or transferring a workpiece.

CNC machine tending combines grippers with pneumatic control equipment to load plus unload components around the machine cycle.

Pick-&-place equipment can use pressure-maintenance hardware as part of the wider gripping circuit.

Production automation may require an existing 1078823 valve to be identified during preventative maintenance, machine refurbishment or pneumatic troubleshooting.

Gripper repairs can involve the valve when investigating damaged connections, air leakage or unexpected changes in holding behaviour.

Product Selection Guide

Found 1078823 On The Existing Valve?

That manufacturer reference gives you an excellent starting point. Do not stop there.

No item number visible? Start with the gripper identification plate or machine documentation before measuring the valve.

A maintenance technician may see a compact block with four connections plus assume another pneumatic valve will perform the same job. That is exactly where model identification matters. Internal function is more important than external resemblance.

When dimensions, fittings or neighbouring components need checking during service, Measuring & Layout Tools can support the inspection process.

Expert Tips

Keep 1078823 with the machine record. Recording the valve reference beside the corresponding gripper model can make future identification considerably faster.

Map A1, A2, B1 & B2 before touching the tubing. Mark or photograph every line before disassembly.

Diagnose the circuit—not just the most obvious component. A damaged tube, leaking connector or supply problem can create symptoms that resemble a valve fault.

Inspect the four G1/8 connections carefully. Thread condition, sealing plus correct reconnection all matter during replacement.

Never select by appearance alone. Two compact pneumatic valve blocks can perform completely different functions.

Remove stored pressure before servicing pneumatic equipment. Follow the applicable machine isolation plus Röhm servicing instructions.

Watch tubing during the full machine movement. Robot travel or repeated articulation can place loads on hoses plus fittings that are difficult to see while the cell is stationary.

Verify operation after reassembly. Returning the lines to their original positions is only part of the job; the complete system needs to operate as intended before production resumes.

For hard-to-see connections inside guarded equipment or behind mounting plates, Inspection Mirrors & Lighting can make visual checks easier.

Is The Valve Actually Causing The Pressure Problem?

Not every pressure problem starts at the pressure safety valve.

A useful troubleshooting sequence begins upstream.

First, check the supply. Is compressed air reaching the system at the required operating condition?

Next, inspect the tubing. Look for cuts, abrasion, tight bends, crushing or movement around the robot or machine.

Then examine the fittings. A leaking pneumatic connector can reduce pressure without any internal valve fault.

Now inspect the 1078823 installation. Compare A1, A2, B1 & B2 with the existing circuit information plus look for obvious damage or disturbed connections.

Finally, consider the gripper itself. Pressure behaviour needs to be assessed as part of the complete pneumatic system.

This sequence helps avoid replacing the valve simply because it sits near the symptom.

Loose fittings plus small pneumatic parts can also disappear quickly in a busy maintenance area. Drawer Organisers provide a practical way to separate identified spares, while Tool Maintenance Kit supports routine workshop equipment care.
