Pressure Safety Valves
was founded in 1959. Since 1962 has been manufacturing Safety Valve for industry in general and in particular, for the petrochemical, chemical and refining industry, power boilers and steam plants.
The range of type, dimensions and ratings is vast and can satisfy the most varied and complex requirements. Quality is guaranteed by our Company’s quality system which is operated by highly qualified personnel under the guidance of authoritative management in accordance with ISO 9001.
All our activities follow the rules given by a management system for environment and safety, approved by third party, in accordance with EN ISO 14001 and OHSAS 18001.
Experience, the importance given to research and experimental work and the quality of our products have classed the company as one of the most important and innovative manufacturers of these types of valves in the European market.
Following results of tests and controls, our valves have been approved by ISPESL (ex ANCC), RINA, LLOYD’S Register of Shipping, DNV, TC (ex GOST), SELO People’s Republic of China, BV.
From year 2010 we can supply valves with ASME VIII stamp for serial 3000A 3000W, 4000, 4000W and 9000. All valves shown in this catalogue (except low pressure Series 6000L) are supplied, when the Pressure Equipment Directive is applicable, with CE marking and declaration of conformity.
Product Range
• Spring Loaded-Full Nozle Safety Valves
A. Safety Valves Flanged - Bolted Bonnet Type
B. Safety Valve with Threaded or Flanged Connections
• Pilot Operated Safety Valves
• Low Pressure Pilot Operated Safety Valves
• Taimatic-Electrically Operated Valves
• Spring Loaded-High Pressure Steam Safety Valves
• Changeover Pressure Safety Valves
For the installation of 2 (two) safety valves, one in operation and the other on stand-by. A changeover
valve can be installed at the inlet and a second one at the outlet of a couple of safety valves
and be mechanically interlocked for simultaneous operation. Sizes 1” – 14”.
• Pressure Relief Pin Devices (PRPD)
Pressure Relief Pin Devices (PRPD) is applicable in model 3000H-PRPD, designed for critical applications. The PRPD offer a high end technology and smart solution that make the deformation of the pin at the set pressure will depend on the free stroke of the nozzle and will be such as to induce a plastic and unrecoverable deformation in the pin. The device is perfectly tight up to 97% of the set pressure.
• Pin Actuated Pilot Operated Pressure Relief(PAPORD)
Non–reclosing devices operated by buckling pin are also available for our model 9000 and 9000R valve series in order to cover the API 526 range.
