Product catalog summary

Body Pressure Relief Valve Overview
This document provides detailed information on the UGS Body Pressure Relief Valve, designed to protect gate valve bodies from excessive pressure loads. It is particularly suitable for gate valves in pressure seal design.

Main Applications
The valve is used to protect against excessive loads in gate valves, especially those with pressure seal designs. It is suitable for handling water, steam, and other non-aggressive fluids like gas or oil upon request.

Operating Data
The valve operates at a nominal pressure of ≥ PN 40 and a nominal size of DN 15, with a maximum permissible pressure ranging from 25 to 750 bar.

Materials
The valve is constructed from various materials, including P 250 GH, 13 CrMo 4-5, and X 10 CrMoVNb 9-1, each with specific temperature limits.

Design Details
The valve features a forged steel body, a stainless steel valve disc, and an adjustable spring assembly. It includes a stellited seat and a lead-sealed screw to prevent unauthorized adjustments. The design complies with the European Pressure Equipment Directive 2014/68/EU and ATEX 2014/34/EU for use in potentially explosive atmospheres.

Variants
Available variants include models with or without a bursting disc, and options for a blocking device or a lockable shut-off valve.

Product Benefits
The valve offers protection against excessive loads, a long service life, and high reliability due to its robust design and corrosion-resistant materials.

Installation Instructions
The valve should be installed with a pipe connection in a vertical position outside the insulation. It must not be welded directly to the gate valve but connected via a pipe. The blow-off pressure is factory-set and secured against tampering.

Purchase Order Specifications
Orders should specify the type, material, blow-off pressure, and pipe connection details.
