RISING STEM AND HANDWHEEL LINED PASSAGE AND HANDWHEEL RS WITH BONNET & HADNWHEEL NRS
The XD series knife gate is a Bi-directional resilient seated valve with frontal upper sealing
designed to handle waste water, mud, vaccum pump systems and general liquid mediums.
The design of the body and seat ensures a bubble-tight shutoff in both directions of the flow.
GENERAL FEATURES TECHNICAL DATA
100 % water tight in both senses Size range:
U-seat with a steel stiff core vulcanized, fixed between DN-50 (2”) to DN-1800 (72”)
the two bodies by screws.
Without stuffing box Working pressure:
Frontal elastomeric upper sealing DN 50 to DN 200: 10 kg/cm2
Two split body arrangements: semi lugged (wafer) and DN 250 to DN 300: 7 kg/cm2
optionally, fully lug-between flanges and fully lug-end DN 350 to DN 400: 6 kg/cm2
valve without counter flange. DN 450 to DN 600: 4 kg/cm2
Short face-to-face dimension DN 700: 3 kg/cm2
Smooth and unobstructed full flow passage, no cavity or DN 800: 2 kg/cm2
void in body, means no clogging DN 900: 1,5 kg/cm2
Easy drive replacement DN1000 to DN1800: 1 kg/cm2
Self cleaning design; little maintenance required Flange ratings:
Proximity and limit switch mounting points PN10, PN16 and ANSI B16.5 (class 150)
Note: other flange drillings under request
APPLICATION FIELDS Face to face dimension:
According to K1 DIN3202 up to DN-350
Wastewater treatment Coating:
Fish handling RAL 5017, 150 microns epoxy coated
Cruises and shipts
Biomass Directives:
Tunnel boring Pressure equipment directive 97/23/CE
Plastic recycling plants DIR 2006/42/CE (MACHINES)
Food and beverage DIR 94/9/CE (ATEX)
Etc. Approved certificate for potable water
(ACS-Atestation De Conformite Sanitaire)

SEAT TYPE
The seat consists of one piece vulcanized u-shaped rubber seat (optionally PTFE) with steel
stiff core inside, fixed between the two half bodies by screws, providing a bubble-tight shut off
on both directions and, avoiding at the same time any build-up of fluids inside the body that
would prevent the valve from closing.
