Watts 530C 1/2" Adjustable Relief Valve

Series 530C Calibrated Pressure Relief Valves are used in commercial, residential and industrial applications to protect against excessive pressure in systems containing water, oil, or air. It consists of a bronze body construction with NPT threaded male inlet and NPT threaded female (drain) outlet connections, stainless steel spring, brass bonnet, Buna-N disc, and Buna-N O-ring. Series 530C has a calibrated adjustment feature for setting the valve to the required relief pressure, and is ideal for by-pass thermal expansion pressure relief (not ASME approved). Model 530FP is for use in fire protection systems

The Columbus Doors, also called the Rogers Doors or Rotunda Doors, stand imposingly at the main entrance to the Capitol, almost 17 feet high and weighing 20,000 pounds. The bronze doors are curved, with a semicircular tympanum above two valves that are divided into four panels each. The details of each scene are finely modeled, and techniques of Renaissance perspective and different levels of relief give each scene a sense of depth. At the pinnacle is a bust of Columbus, surrounded by rays and oak leaves, signifying his rising to glory. A running border is ornamented with Indian headdresses and emblems of conquest, navigation, the arts and sciences, history, agriculture, and commerce. The four figures symbolizing the continents of Asia, Africa, Europe, and America indicate the entire world's acknowledgement of Columbus's accomplishment. Between the panels are sculpted heads of historians and others whose writings on Columbus's voyage were the bases for the scenes depicted. The life of Columbus begins at the bottom of the left valve and continues in a clockwise progression, consisting of the following scenes: - Columbus Before the Council of Salamanca (1487) - Departure from the Convent of La Rabida (1492) - Audience at the Court of Ferdinand and Isabella (1492) - Departure of Columbus from Palos (1492) - Landing of Columbus in the New World (1492) - Columbus's First Encounter with the Indians (1492) - Entry of Columbus into Barcelona (1493) - Columbus in Chains (1500) - Death of Columbus (1506) The American sculptor Randolph Rogers (1825-1892) was asked by Captain Montgomery C. Meigs, the Supervising Engineer of the Capitol Extensions, to design a set of doors for the entrance to the new House wing from Statuary Hall. As a subject, Rogers suggested the life of Columbus. Rogers's estimate for the project was approved on May 24, 1855, and the artist, who had earlier studied sculpture for 3 years in Italy, went to Rome to work on the models. The commission for the Capitol was only his second large public work. The model was completed in 1857 and was cast in 1860 by Ferdinand von Miller at one of the finest foundries in the world at the time, the Royal Bavarian Foundry in Munich, Germany. However, because of delays in transportation, the doors did not arrive in Washington to be installed until 1863. In 1871, they were moved to the central east front entrance. They were moved to their present location in 1961 following the extension of the east front of the Capitol.

HKS SSQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure. The Super SQV will support new generations of turbocharged vehicles. Price RM140 Loc.
