Bonnet

Built-in pressure balance mechanism, consisting:
DN15 ~ 125 is composed of 316 bellows 304 balance spring.
It is very convenient to disassemble and assemble the adjusting mechanism and the actuator (thermostat) through the connecting nut.

implementing agency

The thermostat is a temperature-adjusted actuator. It works according to the principle of incompressible liquid and thermal expansion and contraction. There are two types of thermostats and multiple temperature control ranges to choose from.

Special type

There is no need to lubricate the working environment with special cleanliness requirements.

Dimensions and weight

Note:

1. Flange standard: normal D1N standard (Germany) can also provide users with the following flange standard products, but the order should be specially noted.

JB (China)

ANSI (Customs Country) can only provide ANS1150 and 300

JIS (Japan)

2. H in the table is the height of the whole machine excluding the expected parts.

When adding accessories, the height of the whole machine is the height in the table plus the effective height of the accessories.
