Product catalog summary

Accessories Overview
This document provides technical specifications and arrangements for accessories used in low inertia brakes and clutches, focusing on Quick Release Valves (QRVs) and related components.

Quick Release Valves (Springless)
QRVs are essential for applications requiring rapid response. However, they are not available for 4'' and 6'' units. For these sizes, elbows can be used as alternatives where fast response is not critical. QRVs are available for sizes ranging from 8'' to 48''.

Specifications and Components

W00-10-906 Muffler: Features include a 1/2'' NPT connection, dimensions of 2 23/32'' (69.06 mm) by 5 1/8'' (130.18 mm), and a 7/8''—14 UNF—3A thread.
W00-10-917 QRV with Muffler: Includes a 1/2'' NPT connection and a length of 5'' (127.00 mm).
W00-10-918 QRV with Muffler: Similar specifications as W00-10-917.
W00-10-900 QRV: Features a 1/2'' NPT connection, 37o J.I.C., and a 7/8''—14 UNF—3A thread, with dimensions of 2 7/8'' (73.03 mm) by 1 1/2'' (38.10 mm).
W00-10-901 QRV: Includes a 1/2'' NPT connection with dimensions of 2 11/16'' (68.26 mm).

Recommendations
For applications where fast response is not critical, elbows can be used instead of QRVs. Ensure compatibility with the specified sizes and connections for optimal performance.
