PKTBA-SI-26-1

Test bench for hydraulic and pneumatic tests and adjustment of control valves DN 50…600 мм (2...24'')

Test bench for air and water tests and adjustment of control valve

TEST BENCH FOR HYDRAULIC AND PNEUMATIC TESTS AND ADJUSTMENT OF CONTROL VALVES DN 50…600 ММ (2...24'')

PURPOSE:

• control valve adjustment to allow for the flow rate of the medium;
• testing the housing part materials for strength and density;
• gate leakage tests;
• environmental leakage tests (including gland seals).

TETSTED ITEMS:

control valve.

TESTED UNIT CONNECTION TYPE:

• flanged;
• welding.**
• threaded-end;**
• nipple;**
• true union.**

EQUIPMENT ADVANTAGES:

• The power hydraulic clamp operation without water (from the oil pump station) extends the bench life.
• The two-sided gate seal tests do not require the tested-valve rearrangement, which significantly reduces the test time.
• The bench is equipped with a special system for air removal from the tested item, which improves safety, productivity, reliability of the obtained data, and obviates the need for additional air drain.**
• The bench is equipped with the water-collection tray.
• The test preparation time is significantly reduced by using the high-pressure quick-connect hoses.
• The bench is quickly adjusted to allow for the face-to-face dimensions of a valve using the hydraulically driven cross-head.
• Tiltable cross-head is used to simplify the valve installation procedure before testing.
• All water-wetted parts are corrosion-proof.
• The bench is equipped with replaceable blind flanges for testing non-flanged valves, which releases the operator from welding (lock-pin screwing) of the blind flanges to the pipes and saves up to 30 minutes of their replacement time.
• The mounting and testing processes are fully automatic to facilitate the bench operation (reduced man-hours when working with large valves).
• Increased-diameter hoses reduce the time of the valve filling with the test medium.


The patented pipeline valve test procedure to eliminate axial compression (body deformation).**

CONFORMED WITH STANDARD OF TESTS: API 598; ANSI/ISA-75.19-1995; DIN EN 12266; ISO 5208; ASME B 16.5; ASTME 1003-05; GOST 5762-2002; GOST 9544-2005.


OPTIONAL:
