AI Contract Overview

This contract outlines the qualification test methods and procedures for a selector valve, part number 12008824, intended for use within military or defense applications. The valve must be compatible with MIL-PRF-6083 fluid standards and feature ports conforming to specific drawings. The testing involves verifying the valve’s operability in three distinct positions, ensuring smooth and consistent rotation under hand force. It mandates performance under varying pressures and temperatures, including operational tests at 3,000 psi within 70 to 120°F, with strict criteria against fluid leakage or malfunction. Flow rate minimums are set at 2 GPM for both open and reverse flow positions at the specified pressure. Pressure endurance is rigorously assessed through proof pressure tests at 4,500 psi and burst pressure tests at 7,500 psi, both repeated twice and held for two minutes, with the valve required to withstand these pressures without rupture or excessive leakage. Internal leakage limits are established at 1 cc per minute across all valve positions under the set pressure and duration. Temperature resilience tests at low (-65°F) and high (140°F) temperatures further confirm performance integrity and ease of operation. The contract also specifies no external leakage beyond minor wetting throughout all tests and requires an endurance test comprising 2,000 full duty cycles, followed by a detailed inspection for wear or damage. Overall, the contract sets rigorous standards to ensure the selector valve’s reliability, durability, and safety for military use.

Full Description

SELECTOR VALVE 12008824 QUALIFICATION TEST METHODS AND PROCEDURES 501 Fluid compatibility- The valve shall be compatible with MIL-PRF-6083. 502 Ports All ports of the three (3) positions, four (4) way valve shall have orientations and connections as shown on Dwg. No. 12008800 and 12008801. 503 Operational tests Assure that the valve can be set to all three positions with ease by applying a constant hand force to the handle. The movement of rotational parts should be smooth (constant friction). Set the valve to an open position. Apply 3000 +/- 50 psi at temperature between 70 and 120 F. Turn the handle to the close position. There should be no fluid flow in either direction. Set the valve to a reverse flow position. Apply 3000 +/- 50 psi at temperature between 70 and 120 F. Record the Input and Output pressures, and the temperature. Any malfunction of this valve shall be cause for rejection. 504 Flow rate - Set the valve to an open position. Apply 3000 +/- 50 psi at temperature between 70 and 120 F. With the 3000 +/- 50 psi the minimum flow rate at the fully open position should be 2 GPM. Set the valve to a reverse flow position. Apply 300 0 +/- 50 psi at temperature between 70 and 120 F. With the 3000 +/- 50 psi the minimum flow rate at the fully open position should be 2 GPM. 505 Proof pressure A Proof pressure of 4,500 psi shall be applied at a temperature between 70 and 120 F for at least two successive times and held for a minimum of 2 minutes. The valve should be pressurized in both directions separately as indicated in the Operational test. The valve shall be operated in its normal function between applications of the test pressure. 506 Burst pressure A Burst pressure of 7,500 psi shall be applied at a temperature between 70 and 120 for at least two successive times and held for a minimum of 2 minutes. The valve should be pressurized in both directions separately as indicated in t he Operational test. The valve shall not rupture under this pressure nor shall leakage exceed that permitted in the external leakage test specified herein. This should be the last test performed because of its destructive nature 507 Internal leakage With the valve in the open position, apply 3000 +/- 50 psi hydraulic pressure for 30 min. Repeat the same with the valve in the closed, and in the reversed flow position respectively. The internal leakage shall not exceed 1 cc pe r minute. 508 Low temperature - Set the valve to an open position, and apply 3000 +/- 50 psi. Stabilize the temperature at 65 F for 3 hours. Turn the handle to the close position. There should be no fluid flow in either direction. Set the valve to a reverse fl ow position. Apply 3000 +/- 50 psi. Assure that the valve can be set to all three positions with ease. The movement of rotational parts should be smooth (constant friction). The internal leakage shall not exceed 1 cc per minute. Any malfunction of th is valve shall be cause for rejection. 509 High temperature - Set the valve to an open position, and apply 3000 +/- 50 psi. Stabilize the temperature at 140 F for 3 hours. Turn the handle to the close position. There should be no fluid flow in either direction. Set the valve to a reverse flow position. Apply 3000 +/- 50 psi. Assure that the valve can be set to all three positions with ease. The movement of rotational parts should be smooth (constant friction). The internal leakage shall not exceed 1 cc per minute. Any malfunction of this valve shall be cause for rejection. 510 External leakage - During the course of all of the above tests, external leakage, other than a slight wetting insufficient to form a drop, shall be cause for rejection. 511 Endurance The assembly shall be subjected to 2000 full duty cycles of operation as specified in the Operational Test. At the conclusion of the endurance test, the component shall operate satisfactorily and shall be disassembled and careful ly inspected. There shall be no evidence of excessive wear in any part of the component. Contractors interested in qualifying their product, can contact the POC below.
