摘要： A pressure regulator for dirty fluid service includes: a body having a chamber, a pair of supply sockets, and an outlet port, each socket and the port formed through a wall of the body; a pair of supply seal plates disposed in the supply sockets and having supply passages formed therethrough; and a sliding seal assembly disposed in the chamber. The sliding seal assembly includes: a seal carrier having a piston and a supply gland; and a supply seal disposed in the supply gland. The piston is disposed in a pilot portion of the chamber. The outlet port and sockets are located adjacent to a regulated portion of the chamber. The piston is operable to move the sliding seal assembly between a supply position and a second position in response to pressure differential between the pilot portion and the regulated portion.

摘要： A key seal preferably includes a first circular seal portion, a second rounded seal portion and a third rounded seal portion. The first circular seal portion preferably has generally circular cross-section. The second rounded seal portion preferably has a bottom side which is connected to the first seal portion, and has a cross-section which is smaller than that of the first circular seal portion. The third rounded seal portion preferably has a top side which is connected to the first seal portion, and has a cross-section which is smaller than that of the first circular seal portion. The first, second and third seal portions may be integrally formed. They key seal may be installed in a hydroseal assembly around the pin section of a hydroseal, and between a seal and a block section of the hydroseal.
