M.T.M. VALVES srl is manufacturing Company of forged steel valves for petrochemical industry, chemical and refinering plants, energy power production stations, extraction plants, oil pipeline, off-shore and on-shore plants. Established in 1996, in spite of the young age, M.T.M. VALVES has a staff with pluriannual experience in designing and manufacturing of forged steel gate, globe, piston, ball and swing check valves in size from ¼” through 4”. The production range includes valves in execution BOLTED BONNET, WELDED BONNET and PRESSURE SEAL whit threaded ends NPT, SOCKET WELDING, BUTT WELDING, NIPPLES and INTEGRALLY FLANGED, in class 150 - 300 - 600 - 800 - 1500 - 2500 - 4500 Lbs, fully in accordance with design and construction standard as API 602, BS EN ISO 15761 , ASME B16.34, ASME B16.5, ASME B16.10, API 600, MSS SP84.
M.T.M. VALVES are manufactured in the following materials:
carbon steel ASTM A105 and low carbon steel ASTM A350 Gr. LF2, alloy steel ASTM A182 F5, F11, F9, F22, inox stainless steel ASTM A182 F316, F316L, F304, F304L, F347, F321 duplex stainless steel ASTM A182 F51, F53, F55 and austenitic steel 6Mo ASTM A182 F44, and high nickel alloy steel as MONEL, HASTELLOY, INCOLOY, TITANIUM, INCONEL, strictly in accordance with NACE MR-01-75 standard, when required.
Experience, quality, service, flexibility, and reduced delivery times are the strenght points of the company, which intends satisfy all customer’s exigencies and requirements, in the market of forged steel valves where to have a valve is necessary waiting for long times. The delivery time depends by the required material and by the availability of raw pieces in stock with a minimum of 30/40 days and a maximum of 8/10 weeks.
Quality system is in strict osservance of UNI EN ISO 9001:2008 certified by T.U.V. ITALIA SRL. Every M.T.M. VALVES gate and globe valve is subjected to shell backseat and high and low pressure closure tests. Check valves are given shell and high pressure closure tests fully in accordance with API 598 and ASME B16.34 standards.
Also, under request, it is possible check the valves with magnetic particle inspection, dye penetrant, ultrasonic test, mechanical and chemical analysis, positive material identification, destructive tests, fugitive emission test, low temperature test.
All valves are furnished with identification nameplates in which are marked the type of valve, the rating, the size, the maximum operating temperature and the material of body, bonnet and trim according to MSS SP25 specification. On each body and bonnet is clearly stamped the material and the heat code number, and, obviously, the own trade-mark. M.T.M. VALVES are particularly suitable for high pressure temperature services, especially for steam; in the cryogenic service and low temperatures we assure the maximum safety until 196°C.
For chlorine and oxygen service the valves follow particular degreasing, cleaning and packaging procedures and warrant the perfect use.
For dangerous and toxic fluids we suggest the employment of bellows seal valves. For sour oil and gas services the valves are manufactured and tested in strictly osservance of NACE MR-01-75 standard. The continuos growth of the company, the seriusness, the professionality and the high tecnological machinery are bringing M.T.M. VALVES to take the own space in the market, satisfying the different customer’s exigencies and requirements.
