760X diaphragm relief valve closed

Specifications

Double chamber control 
Valve dual cavity design of the control room situation, according to the different uses of the two chambers can be isolated or connected to each other in order to achieve slow opening, quick closing or slow closing and other auxiliary functions, to a certain extent hindered the generation or water hammer water hammer relief efforts after the valve to protect other equipment from damage;
Reliable corrosion 
Valve cavity, including the upper chamber, the valve stem, the valve plate, valve seats, springs, bolts and flow channel (with media contact points), etc., in addition to stainless steel, copper alloys that were carried out non-toxic spray treatment, with good The overall anti-rust function;

Adjustable stroke 
Top of the valve may need to set the stroke adjustment means, according to the pipeline pressure, flow regulating the size of the main valve plate and the opening height of the valve to achieve the best results apply;

Dual-valve design 
Water control valves according to their uses and characteristics, the valve clapper applicable double or single valve two different configurations to meet different working conditions.

Long pitch guide stem long run using the middle pitch oriented, avoiding the valve cover and the guide holes on the seat due to processing or install a different heart, causing the valve stem movement blocked, easily stuck phenomenon;
Self-balancing function 
Valve sealing loose fitting design, namely the stem. Disc has some holes with the gap between the valve plate in the plane perpendicular to the stem has a certain degree of freedom that can automatically balance the error caused by the processing or assembly seat sealing surface is not perpendicular to the stem defects, to achieve zero leakage;
Throttling structure 
Valve seat at restrictor may need to set some conditions because the actual flow is small, so that the valve is opened just a little on the close, and open and close the valve disc frequently vibrate, causing severe vibration and sealing surfaces pipeline gas cloud In this case, the throttle valve seat can be installed to increase the valve disc travel, to eliminate the phenomenon of vibration, and gas cloud.
760X diaphragm slow closing check valve installed in the main water supply system must prevent the reverse flow of water inside the tubes of the occasion, effectively prevent the reverse flow of water. Opening and closing speed can be adjusted according to actual conditions, respectively, to achieve slow or slow opening and closing.
