Q:How can I get the fire signal butterfly valve?: At the input end of the input module, some resistors or terminals are added to the product

Q:Have an iron block, aluminum heads, solid roller lifters, Jessel rocker shafts, what should my valve clearances be cold, and hot??: On solid lifters tappy is happy I don't have a manual here, but if you need to get it going now that phrase will help you.

Q:What's the difference between electric butterfly valve and electric two way valve?: Below we will be specific to understand the electric two way valve and electric butterfly valve of the difference between.Distinguish one: product performance is different, the electric two way valve is for the central air-conditioning fan coil supporting products; and electric butterfly valve and electric control valve is the same species;Difference two: the product function is different, the electric two way valve is automatic adjustment; and the electric butterfly valve is a variety of adjustment methods.Difference three: product classification is different, the electric two way valve body activities are more piston style structure; and butterfly valve structure is diversified, such as sealed form can be divided into soft sealing and hard sealing type of two.

Q:How do i use a valve spring compressor. It looks like a c-clamp, so don't tell me how to use a smaller one, but the bigger one.Thanks: The forked end goes over the valve retainer, the flat end with the screw goes against the valve face. Simply close the handle to compress the spring. You may need to adjust the width of the jaws to fit the retainer and adjust the length of the screw to compress the spring the right amount. Sometimes it helps to gently tap the edge of the retainer with a hammer to loosen the keepers before compressing the spring.

Q:What's the meaning of butterfly valve d371po?: According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)

Q:What are the classification criteria for pneumatic butterfly valves?: Pneumatic flange butterfly valve, pneumatic flange butterfly valve, this product is made up of rubber sealed butterfly valve and carbon steel or stainless steel valve plate and valve stem. Suitable temperature is less than or equal to 80 to 120 DEG C, such as food, chemical, petroleum, electric power, textile, papermaking, water supply and drainage, gas pipes to regulate the flow and closure of the role of media.Pneumatic control valve is a valve (valve plate) around the rotating fixed axis perpendicular to the channel, which is composed of double or single acting piston (spring reset type) pneumatic actuator and butterfly valve, a rotary type high performance adjust or cut off valves, electric, pneumatic valve positioner or electromagnetic valve, air filter regulator, limit switch (valve position), can be realized on the fluid medium in the pipeline and process to adjust the proportion of the two cut off control, automatic control to achieve the parameters of the fluid flow, pressure, temperature, liquid level etc..

Q:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?: Signal butterfly valve is generally can achieve full clearance of a valve opening electrical signal output, the general requirements of the electrical signal isPassive electric shock signals are mostly used in fire fighting systems, such as the need for valve position feedback;The electric butterfly valve is not necessarily the signal butterfly valve, because the electric butterfly valve does not have the requirement of the source contact.

Q:What's the material of the butterfly valve seat?: Butterfly valve seat materials commonly used include EPDM (three yuan ethylene propylene rubber), NBR (Ding Qing rubber), PTFE (PTFE), metal sealing (cemented carbide).Their scope of application is..:1, EPDM (three yuan ethylene propylene rubber): excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor, color stability, electrical properties, oil and gas flow at room temperature. Ethylene propylene rubber products can be used at 120 degrees for a long time and can be used briefly or intermittently at 150-200 degrees centigrade.2, NBR (Ding Qing rubber): from butadiene and acrylonitrile was prepared by emulsion polymerization, nitrile rubber by emulsion polymerization at low temperature, excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are poor resistance to low temperature, poor ozone resistance, poor electrical properties, and slightly lower elasticity.3, PTFE (polytetrafluoroethylene): can be used at 260 degrees for continuous use, with the highest use temperature of 290-320 degrees, low coefficient of friction, good wear resistance, and excellent chemical stability. It can not be injection molded and can be extruded or painted. PTFE's unique properties make it widely used in chemical, petroleum, textile, food, paper making, medical, electronic and mechanical industries and marine operations.4, metal seal (hard alloy): metal seal valve seat material has good resistance to high temperature, high pressure resistance, corrosion resistance and wear resistance, but the high requirements of the processing technology, the biggest drawback is the long time operation is easy to generate leakage.

Q:In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?: Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.

Q:What are the advantages of butterfly valves?: Butterfly valve, also known as shutter valve, its advantages are:A. has a large circulation capacity and is about 1.2 times the same size as two seat valves;
