Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang SPENCE dari 3G Electric.
What types of steam traps does SPENCE offer?
SPENCE offers standard inverted-bucket steam traps in cast iron, designed for horizontal in-line installation. These traps are available in sizes from 1/2 in to 1 1/2 in FNPT, with capacities ranging from 690 lb/hr to 10,000 lb/hr and maximum pressure ratings up to 180 psi. Some models include integral strainers, while others require external strainers. The inverted-bucket design provides reliable condensate removal and is suitable for varying load conditions in steam systems.
What are the specifications of SPENCE pressure regulators?
SPENCE pressure regulators, such as the D50A series, are cast iron general-purpose units with FNPT connections. They are available in sizes like 1 in x 1 in, with adjustable set points from 2 psi to 30 psi and a maximum operating pressure of 20 psi. These regulators are designed for steam and air service, providing precise pressure reduction. They feature a diaphragm-operated design for responsive control and are suitable for industrial and commercial applications.
What materials are used in SPENCE pneumatic globe control valves?
SPENCE pneumatic globe control valves, such as the K1TC811-36RA, feature a bronze body with FNPT x FNPT connections and a stainless steel disc. The valve operates with an air-to-spring actuator, providing fail-safe action. The bronze construction offers corrosion resistance in steam and water applications, while the stainless steel disc ensures durability under high-pressure conditions. These valves are available in sizes like 1/2 in and are suitable for modulating control in steam systems.
What is the maximum temperature rating for SPENCE air vents?
SPENCE air vents, such as the NAV-213, are rated for a maximum temperature of 500°F and a maximum pressure of 400 psi. These vents feature a stainless steel body and are designed for in-line, vertical-discharge installation with a 3/4 in MNPT top port connection. They automatically remove air and non-condensable gases from steam systems, improving heat transfer efficiency and reducing corrosion.
Are SPENCE steam traps available with integral strainers?
Yes, some SPENCE steam traps, such as the 81S-C1E9 and 81S-C7E9, include integral strainers, while others like the 85-CPG9 do not. The strainer helps protect the trap from debris and extends service life. Models with strainers are identified by the 'S' in the part number. It is important to verify the specific model's specifications to determine if a strainer is included or if an external strainer is required.
