Universal Thermodynamic Steam Trap (for use with Universal Connector)

Description

The Thermodynamic steam trap cycles periodically to discharge condensate very near to steam temperature. It is unaffected by waterhammer or superheat. The UTD is a unique solution to maintain the disc in the horizontal plane by means of a universal connector.
The trap is easily replaced or removed for servicing without disturbing the pipe connections.

Sample Specification

Steam trap shall be supplied with a pipeline connector which, once installed, remains in the line permanently. Trap shall be attached to the connector by two bolts to enable simple and rapid installation and replacement.The connection is designed to allow installation on pipework that is vertical, horizontal, or any angle in between. Operation shall be on/off discharge with tight  shut off and no bleed or “controlled” leak, with back pressures up to 80% of inlet pressure. When specified, the connector shall be provided with integral “Y” pattern strainer with or without integral blowdown valve, standard or left hand pattern. The trap itself shall be Thermodynamic disc type of stainless steel construction and integral seat design with hardened disc and seating surface. Cap to have integral ceramic insulator with stainless steel cover. Determining whether you need Standard Strainer Connector or Left Hand — Because of location or space constraints, when straddling the pipe facing in the direction of flow the standard strainer connector wih the trap body facing the left side with bolt on the right. The left hand connector will have the trap body on right with the bolts on the left.

Installation

The connector can be installed in horizontal or vertical lines. The connector face must be in a vertical plane. The trap should be fitted to the connector with its cap uppermost. Full-port isolating valves should be installed upstream and downstream of the connector.

Maintenance

The trap can be removed for repair or replacement without disturbing the connector piping connections. Complete isolation of the connector from both supply and return line is required before the trap is removed.
The trap should be removed from the connector and disassembled periodically for inspection and cleaning of the disc and seat.
Complete installation and maintenance instructions are given in the IM-2-5161-US, which accompanies the product.
