valves must be zero leakage. bronze gate globe & check valves are usually only tested per mss sp-61 ‘pressure knife gate valves refer to mss-sp81 leakage rates for metal seated (for resilient seat refer to mss sp-61 or the manufacturer or client will nominate leakage).
unlike many other knife gate valves delta industrial™ valves guarantee no process fluid will sneak past your closed valve – protecting your people plant and the environment. to ensure you maintain consistent plant operation and minimise downtime utilise a zero leakage valve on your site.
1. mss-sp81 does not apply to resilient seated knife gate valves. the emerson standard for the pcs17 and f17 is zero leakage of water from 1 to the full rated pressure of the valve. 2. mss-sp81 does not apply to slide gate valves. however emerson applies this standard for valve sizes nps 2 - 12 (dn 50 - 600) with standard seating. 3.
before valve. gabe newell learned about business from his first employer bill gates "that success in software comes from getting outside developers to write programs that sell more copies of your own".gabe newell is listed as the 271st employee at microsoft and he shares something in common with the founder bill gates as they both dropped out of harvard university.
delta industrial™ knife gate valves can guarantee plant operators in difficult process applications zero leakage john abbott weir minerals global product manager for valves confirms.
the rigid gate and the abrasion resistant properties of urethane allow for our valve to seal time after time again and again regardless of how often the valve is actuated. cycle a newcon valve daily or just annually and you will get the same result – zero down-stream leakage… zero atmospheric leakage. clean and safe work environment.
experience zero leaks with a true knife gate valve for many years plant operators have battled with leakage problems searching for valves which will isolate the flow and prevent leaks to the atmosphere but are often left feeling frustrated and out of pocket.

before we start i'm going to be making extensive use of the quadrant naming system as used in describing graphs in math. starting in the (++) area this is marked as q1 shorthand for quadrant 1 and moving around in a counterclockwise motion we have q2 q3 and q4.
