3. Feature:

This valve is mainly composed of body, butterfly plate, valve shaft, seat and transmission devices. Simple and compact structure, small portable, convenient for transport, install and dismantle. 90 degrees of opening and closing, switch quickly, operating is small, light energy; Sealing performance is good, service life is long, can achieve zero leakages. Flow curve tending to straight line, excellent regulation performance.

4. Sealability:

The valve for rubber seal, closing butterfly plate and seat sealing performance is good, two-way sealed good performance and the torque is small. the friction is very small between butterfly plate and the seat seal. The valve shaft drive the butterfly plate, butterfly plate do 90 degrees rotation. Butterfly plate flexible for opening and closing, no card acerbity, beating phenomenon, small torque.

Q: Classification of telescopic butterfly valve: (2) temperature butterfly valve. 120 C<t<450 C butterfly valve(3) normal temperature butterfly valve. One 40C<t<; 120 C butterfly valve(4) low temperature butterfly valve. One 100<t< one, 40 C butterfly valves(E) ultra low temperature butterfly valve. T< one, 100 C butterfly valve (1) clip butterfly valve(2) flanged butterfly valve(3) lug butterfly valve;(4) welded butterfly valve

Q: Import electric butterfly valve which brand is more reliable?: Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.

Q: What's the difference between D71X-16 and D71H-16 butterfly valves?: First, model D71X model means that, on behalf of 7 representative D butterfly valve, butterfly valve connection form for clamp connections, 1 straight, X represents the seal in the form of soft sealing, the sealing surface usually NBR H metal seal is usually 2Cr13 16 represents the pressure of 16 kg pressure weldingJin Ya valve is the production of hard sealing butterfly valve or soft sealing butterfly valve line leader, what problems can ask their units, technicians will answer for you

Q: I went online to check where was the pcv valve for a 2001 ford focus, but I didn't find it. Does anyone have a picture? Thanks: Go around to the passenger side of the car and shove your arm way down along the firewall behind the engine. Feel around with your fingers and you will feel the PCV hose where it connects to the intake. Once you have found that you can follow it forward from underneath (no kidding) about a foot to the PCV valve. I don't think it is even visible from the top.

Q: What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?: Eccentric butterfly valve is divided into single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve, variable eccentric butterfly valve.Single eccentric butterfly valve: extrusion problems, address concentric butterfly valve and valve seat of the resulting in a single eccentric butterfly valve, the structural characteristics of the stem axis deviated from the disc center, so that the butterfly is no longer a rotary bottom plate, axial dispersion, reduce the excessive squeezing and the lower end of the seat of the butterfly board.

Q: What does butterfly valve do?: 5, connections are flanged, wafer connections, welded connections and lugs on the clip connection. ?Drive in the form of manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic linkage actuator, can realize remote control and automation.Advantages of butterfly valves1, opening and closing convenient, fast and labor-saving, fluid resistance is small, you can often operate. ?2, simple structure, small volume, light weight. ?3, to transport slurry, accumulation of fluid in the pipe outlet at least. ?4, under low pressure, can achieve a good seal. ?5, good regulating performance.Disadvantages of butterfly valve1, use pressure and working temperature range is small. ?2, poor sealing. ?Butterfly structure can be divided according to the bias plate, vertical plate, inclined plate and lever type. According to the form of sealing can be divided into soft sealing type and hard sealing type of two. The soft sealing type usually adopts rubber ring seal, and the hard sealing type usually adopts metal ring seal. ?By connection type can be divided into flange and clamp connections; press can be divided into manual transmission, gear transmission, pneumatic, hydraulic and electric types.

Q: Types of butterfly valves: Butterfly valve structure categories: central to clip butterfly valve, central flange butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, eccentric butterfly valve, soft sealing butterfly valve, hard sealing butterfly valveButterfly drive categories: handle, worm gear, electric, pneumatic, electromagnetic, electromagnetic, hydraulic, electro hydraulic, hydraulic, hydraulic, pneumatic

Q: What is the national standard for clip butterfly valves?: GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"

Q: i just finished installing a sprinkler line for my lawn and i used anti siphon valves and 4quot; sprinkler heads. it says in the manual that it has to be at least 6quot; from the highest sprinkler. i think i made a mistake. i installed it 7quot; from the highest 'sprinkler line' . will i have a problem with that regarding the operation of the anti siphon valves and the sprinkler system itself?: anti siphon valves are junk. just install regular valves and put in a backflow preventer on your mainline before all the valves, but right after the shut off vavles.
