HVR-20K-FA Relief Valve — Hand Adjustment up to 20,000 psi

The HVR-20K-FA relief valve offers manual adjustment with a 690–1,380 bar working pressure range. Its maximum working pressure is 1,380 bar / 20,000 psi, making it a choice for pressure protection in high pressure equipment.

This model features a 1/4 in HP female inlet and a 1/4 in NPT female outlet. For OEM buyers and system builders, the defined inlet and outlet types help establish the correct connection requirements early in the project.

Product Specifications

Adjustable Pressure Protection for Your Equipment

Manual adjustment allows the valve pressure setting to be configured for the intended service. This is useful when equipment specifications call for a defined relief setting within the model stated range.

When selecting, provide both the normal operating pressure and the required relief setting. These values give the technical review a clear starting point. Also include the expected pressure changes during operation so the valve can be assessed against the full duty.

HP Inlet and NPT Outlet Connections

The HVR-20K-FA uses different connection types at its inlet and outlet. The inlet is specified as HP female, while the outlet is NPT female.

Although both connections have a nominal size of 1/4 in, each requires a matching fitting. Therefore, list the full connection description on your drawing and purchase order.

When planning the assembly, review the required high pressure fittings together with the valve. Also allow access to the adjustment point and provide a suitable route for the relief discharge.

Specification Support for OEM Purchasing

A complete purchase specification helps engineering, sourcing, and assembly teams work from the same requirements.

For the HVR-20K-FA, include the model number, required relief setting, inlet connection, and outlet connection in the equipment bill of materials. Add any project-specific documentation or inspection requirements to the inquiry.

For repeat builds, retain the approved configuration with the part reference. This supports consistent ordering across production batches and replacement purchases.

Define the Duty Before Ordering

The maximum working pressure is one part of valve selection. Required relief flow, operating medium, temperature, and outlet conditions also affect suitability.

Include these details when requesting pricing. In particular, state the required discharge capacity and any outlet back pressure. This allows the proposed valve configuration to be checked against the application.
