Features

Main control valve

Lifted seat to avoid damage due to cavitation

High Kv value at fully open position

Geometry of regulating plug provides high ratio of travel against Kv, resulting in optimal control performance

Non-symmetric axial position of rubber diaphragm results in less stretch/stress near closed position

All non-coated internals made of stainless steel AISI 316

Body and bonnet of ductile iron with fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901 and WRAS-DVGW/W270/UBA, 100/300micron, GSK approved, RAL 5017.

Pilot system (EP patent No. 2855989)

Modular and compact design for easy application change

Main components made of stainless steel AISI 316:

Distribution block:-  Connecting main control valve to pilot system-  Independent adjustment of opening and closing speed of main valve-  Control orifice

Filter:- High capacity, easy to flush with possibility of back flushing- Mesh 100, high performance wire screen type

Hydraulic control block:- Includes balanced pilot valve providing more stable pressure set- Can be set up for different applications, using single-function modules (SFM) or multi-function modules (MFM)

Optional
