1962-1970

New Penza branch of Central design bureau of valve industry was commissioned in June 1962. Development of pipeline valves for oil and gas industry, chemical plants, rockets and submarines was the main objective of 52 highly-qualified specialists. In short time firm foundation for the forthcoming company development was laid. During this period number of staff grew up to 363 people, facilities enhanced, modern equipment was installed.  In 1965 engineering building of 3 thousand sq.m. was constructed. A year later experimental production base of 5 thousand sq.m. was commissioned.

1970-1980

Move towards the development of technologies, tooling, equipment for production of pipeline valves. 282 standard sizes of new industrial valves were manufactured and put into production according to the branch developments.  Design of valves for the grand and challenging project – Kiev chemical plant for ammonia production was performed. Valves for the most poisonous and strong solvent have to conform to high requirements regarding tightness and working capacity. Development of valves for nuclear power plants was conducted. Wide range of equipment was produced: unmanned manipulators for assembling/disassembling of pipeline valves stamps, semiautomatic devices, development of the conveyer production system for assembly the stamp-welded valves, manipulators for transportation of details from one welding cabin to another.

1980-1990

In the new decade company became the leader in development and production of pipeline valve repair equipment. Development and production of non-standard equipment started: valve test benches, valve repair equipment, welding and overlaying equipment, valve grinding equipment, assembly lines. Substantial innovative works were performed: development and introduction of electroslag casting technology, important shaped blanks and remelting of the high-alloy steel waste.   Production of our company was used by 18 plants of the Soviet Union.

1990-2000

On January 31, 1990 № 55 the branch was renamed by the order of Mintyazhmash of the USSR into the Penza design engineering bureau of valve industry – PKTBA. In 1992 PKTBA was transformed into a joint-stock company.  
The heavy changes happening in the country those years inevitably affected our company. Demand for development of valves fell sharply and as a result a number of departments ceased to exist. The number of employees was sharply reduced.
However, despite all the difficulties, the company staff did their best for further development of PKTBA. Company studied various ways for increasing the orders, searched the new ways for increasing competitiveness and production.
As a result, qualified commercial department was created, and thereby an increase in orders volume followed. From 1995 to 1998 the orders volume for production of PKTBA was increased by 3 times.
Since 1996 production of complexes for technical inspection of gas cylinders has begun.

2000-2010

Equipment for pipeline valves test and repair actively developed and improved. The geography of sales extended: Indonesia, Thailand, Middle East and North Africa, USA, Australia, European Union countries, etc.
The new markets demanded an increase in production capacity, and the corresponding quality of the production. In 2007 new production shop was constructed and equipped with the modern machining centers HARDING TALENT, redesign and repair of production shops was carried out. PKTBA production equipment was significantly updated.

2010 – 2018

In 2012 CJSC PKTBA celebrated its 50-year anniversary. During those years the company has become the leader in the branch and remained the only operating company from the branches of Central design bureau of valve industry since the 60s. In 2013 PKTBA created the International Commerce department, the first contracts with Belgium and the Czech Republic were performed. Work of International Commerce department allowed to expand geography of deliveries considerably: Bolivia, Spain, Great Britain, Italy, Austria, Egypt, Saudi Arabia, Oman, UAE, India, etc. Since 2015 the program for production units update started. The new equipment was purchased: hardening furnace, modern belt-saw and milling machines, radial boring machines. New gates were installed in the shop, ventilation was installed.  

In 2016 2 patents were acquired. Stable quality of production is provided by the quality management system certified in compliance with the requirements of ISO 9001:2015 by certification authority "TUV Thuringen" (Germany).

In 2016 PKTBA introduced the new brand – REVALVE for international business. High technologies, stable quality and qualified personnel are fundamentals of REVALVE brand.

The new range of the equipment presented by horizontal and vertical test benches was presented. The maximum clamping force of the new horizontal clamping equipment was expanded up to 4000 t.

2017.
CJSC PKTBA celebrated its 55-year anniversary. Today the company is the leader in the branch. In many respects we owe this success to our employees. Keeping and increasing experience of the senior generations we move forward!
