QUALITY CONTROL EQUIPMENT In order to assure that WALWORTH products comply with international quality standards, in-house equipment is kept for monitoring control, some of this equipment includes:

X-Ray Examination Equipment. WALWORTH has its own Ir-92 source in-house for the radiographic examination (RT) of castings from 0.100” up to 2 1/2” wall thickness to verify the soundness of the casting raw material.

Magnetic Particle Test. On a random basis for standard products or when a &XVWRPHU� UHTXHVWV�07�&HUWLÀFDWLRQ��WALWORTH has Magnetic Particle Test Equipment to perform on ferromagnetic materials.

Test Loop. A complete Laboratory Test loop exists for design validation of WALWORTH products. The test is performed at maximum design pressure, advances the valves from 3000 to 5000 cycles, and requires more than four months to complete.

Penetrant Test Examination. WALWORTH has the personnel and materials to perform PT examination by solvent removable or water washable techniques. 1'7�SHUVRQQHO�DUH�$617�&HUWLÀHG�

Pressure Gradient Test Loop. This test exposes Plug valves to the extremes of both positive and negative pressure gradients to verify that the plug in a balanced plug design will prevent lock-up in the body.

SLAB GATE VALVESWALWORTH Slab Gate valves are manufactured and tested in accordance API-6D. This type of valve is very useful in transportation pipelines for gas, crude oil, and oil products. The Slab Gate valves are thru-conduit and piggable. The slab gate when opened interior has been designed to minimize pressure drop and catch foreign materials into the disc cavity and also avoid WKH�WXUEXOHQFH�RI�WKH�ÁXLG�WKURXJKRXW�WKH�YDOYH�

WALWORTH Slab Gate valve uses the resultant force from line pressure to help to have a Mechanical and tight sealing in downstream side when high differential pressure occurs. Low pressure sealing is achieved by internal springs assisting in pushing the seat ring against the gate to obtain the seal.

WALWORTH offers this product line in the following base materials:

a) Carbon Steel such as WCB.b) Carbon Steel for NACE Applications like WCB with 0.25 % C maximum and 22 HRc maximum hardness.c) Low carbon steel for low temperature service like LCB.d) Stainless Steel like CF8M.

SAFETY VALVES, RELIEF VALVES AND SAFETY AND RELIEF VALVESThese valves work to release overpressure in a piping system. WALWORTH offers these kinds of valves as a solution for the automatic release of pressure from either a boiler, pressure vessel or other systems when the pressure or temperature exceeds preset limits. WALWORTH offers the following types of valves:a) Safety Valves.- These valves are made from Bronze and used for gas and steam only. Its main use is to relieve the pressure from the system such as boilers, autoclaves, compressors, steam generators, pressure vessels, bronze air or gas pipelines.b) Relief Valves.- This type of valve is typically made from Bronze and used only for water service. Its purpose is to release of pressure acting due the static pressure of the liquid against the vessel or container, releasing the pressure accordingly with the increase of pressure over the opening pressure, protecting the equipment or system of damage. Only used for liquids it is commonly used in bronze tanks, pipelines or other vessels where is not required a big relief capacity.c) Safety and Relief Valves���7KLV�GHVLJQ�LV�PDGH�IURP�FDUERQ�VWHHO��RU�VWDLQOHVV�VWHHO�DQG�PD\�EH�XVHG�IRU�DQ\�ÁXLG��JDV��VWHDP�RU�ZDWHU���7KLV�is a valve which automatically releases the pressure when the over pressure is achieved and can be used as a Safety Valve or a Relief Valve depending on application.
