Brass components produced for gas and drinking water installations with quality awareness meet generally recognised state-of-the-art standards and are manufactured by us according to strictly monitored quality and test criteria.

TYPE: DIN EN ISO 228 | PN 10

MATERIAL: made of pressed brass to DIN EN 12164 / 12165, according to German Drinking Water Ordinance (TrinkwV) basis for metallic materials in contact with drinking water

the heart of a heat interface unit

AREAS OF APPLICATION:

Decentralized home stations for hydraulic proportional changeover “without auxiliary energy” from heating operation to domestic hot water operation

• hydraulic
• proportional flow regulator
• as a replacement/spare part for standard stations/products

ADVANTAGES:

• 100% lead-free brass made from CW724R
• stainless steel 1.4404 Stainless steel push rod
• 3-fold O-ring seal with water-free wetted O-ring incl. grease chamber, separate from the heating part
• heating sleeve rotatable for setting different flow rates
• 3-fold O-ring seal separate from the sanitary part
• optimized closing mechanism for damping closing noises at high differential pressures
• improved ease of installation due to shortened spring protrusion at the “3rd way” connection and improved direct connection of standard T-pieces

ONE product for TWO applications

• suitable for different station types
• with all connections, no conversions necessary!

AREAS OF APPLICATION:

Heat interface units are decentralized water heaters, combined with direct heating or underfloor heating and are individually tailored to your building services project.

ADVANTAGES:

• hot water of high hygienic quality at all times
• production directly on site by means of a heat exchanger using the flow-through principle
• Individual heating comfort - 365 days a year
• low space requirement without storing hot water
• without combustion in the home
• heat interface units can be used regardless of the energy source = ideally equipped for future heating systems
• low flow temperatures possible = energy-efficient heating system
• ohptimum efficiency due to low return temperatures

Combined free-flow and check valve with non-rising stem with test plug and drain valve

TYPE: DIN 3502 / DIN EN 1213 / DIN EN 13959 | PN 10

NOISE EMISSION: DIN 4109 Valve group I

MATERIAL: made of pressed brass to DIN EN 12164 / 12165, according to German Drinking Water Ordinance (TrinkwV) basis for metallic materials in contact with drinking water, Spring material made of stainless steel

ELASTOMERS: double-O-ring seal, EPDM, KTW, W270
