Product Description

Overview

Z45X Z41X, special fire signal gate label: fire, special, lights, gate time: 2017 07 month 10 days reading 1 times Z45X, Z41X signal, in addition to the special fire valve with elastic valve seat seal good, and can more intuitive performance of the valve opening degree, so as to be able to in the opening is the distance discriminant of the valve, to take timely response measures. Open and close is agile and reliable, so it is often applied to the fire system.

Product structure features:
Nominal pressure: 1 ~ 2.5MPa working temperature: 0~80 centigrade flange standard: GB/T 17241.6 GB9113
Nominal: 50 ~ 400mm suitable medium: water, oil, gas and other test standard: GB13927 AP1598
Group rubber valve core
The high performance rubber and the latest vulcanization technology are applied to the spheroidal graphite cast iron framework, which is tightly packed, tightly sealed, geometrically correct and well sealed. It completely isolates the valve core from the fluid and corrosion-resistant.
Integral copper nut
The copper nut and the nodular iron skeleton of the spool are tightly connected with the special technology, ensuring the long-term operation and the impact of the water will not loose, so as to avoid the failure of the valve control.
Flat bottom seat
Our company's elastic base seal gate valve adopts the longitudinal design of the whole basin, which is equal to the pipeline and is not easy to accumulate debris. It ensures reliable sealing and makes the flow smoothly and unimpeded.
Self sealing valve cover
The design of self sealing structure is adopted between the valve cover and the valve body. In the allowable pressure range, the higher the pressure of the fluid, the tighter the seal is.
Specially sealed
The upper sealing structure between the valve stem and the valve cover is designed by three o seals. Compared with the traditional gate valve packing seal structure, the road seal is tight, and the friction resistance is greatly reduced. The valve is at any opening, pressure and safety locking function of the stem. It ensures that the stem is not released by pressure during operation and maintenance, so as to avoid causing personnel hazards.
Light structure
The compact structure enables the maximum working height to be reduced by more than 60mm-300mm compared with the traditional gate valves, and saves the engineering space. The body adopts ductile iron material, and its weight is reduced by about 20%-30% compared to the traditional gate valves, so the installation and maintenance is convenient.
Hygienic requirements for food grade
The inner part of the valve body is painted with nontoxic epoxy resin, and the inside and outside appearance of the valve core is completely covered by rubber, and no signs of rust or corrosion will appear. It can be directly applied to drinking water system and food and pharmaceutical industry
