Product details
Introduction
Main hydraulic gate valve, hydraulic seat plate valve, safety butterfly valve, grate, etc. In the machinery and industrial equipment-valve industry has been recognized by our customers. The company adheres to the business philosophy of "guarantee first-class quality and maintain first-class reputation", and adhere to the principle of "customer first" to provide quality services to our customers. Among them, the hydraulic pipeline gate valve produced by our company adopts a new floating seal structure, which is suitable for pressures up to 2500 grade. The temperature on the oil and gas pipeline is -101 ℃ ~ 350 ℃. The opening and closing and adjustment of the control medium are manual devices. New structure design.

Features of Hydraulic Through Conduit Gate Valves:
1. The floating seats can automatically discharge when the pressure in the middle cavity is too high, and protect the valve safety (see the figure below). When the middle cavity pressure P3 (Pb) is greater than the channel pressure, the middle cavity pressure will release pressure to the channel. When the channel pressure P1 (Pu)> P2 (Pd), the middle cavity pressure is released to the channel at P1 (Pu) side. When the channel pressure P1 (Pu) = P2 (Pd), the middle cavity pressure can be released on both sides of the channel.
2. Technical features of the stem sealing structure
A triple seal structure of O-ring, sealing packing and sealing grease are adopted for stem sealing to ensure that no leakage from the stem sealing pair. It can realize double sealing of packing and O-ring and online replacement of packing.
3. The seals are stainless steel with flexible graphite, same high quality low-carbon stainless steel 316L for body and bonnet to be used for seals or special corrosion resistant alloy designated by the user.
4. Structure of sealant injector
5. The sealing pair of seat and gate is made of cemented carbide metal-to-metal seal and PTFE soft seal. When the soft sealing material is burnt out, the finely processed cemented carbide sealing surface is tightly attached under the action of the spring and the differential pressure of the medium, combined to form a metal-to-metal hard surface sealing.

Product Advantages
1: It adopts a new floating seal structure, which is suitable for pressures up to 2500, and the temperature on oil and gas pipelines is -101 ℃ ~ 350 ℃.
2: It is made of stainless steel with good glass. At the same time, the products also have corrosion resistance and high temperature resistance. Beautiful appearance and other characteristics.
Quality Control Activities
1. Type and accuracy
Test pressure measuring devices shall be either pressure gauges or pressure transducers which are accurate to within ±2,0% of the full-scale reading.
2. Gauge range
Pressure measurements shall be made between 25% and 75% of the full pressure range of the measuring device.
3. Calibration procedure
Pressure-measuring devices shall be periodically recalibrated with a master pressure-measuring device or a deadweight tester at 25%, 50%, 75% and 100% of the full pressure scale.
4.Temperature–measuring devices
Devices for measuring temperature, if required, shall be capable of indicating and recording temperature fluctuations of 3°C (5°F).
FAQ
Q: How to install?
A: Can use directly after connect electric.
Q: How long is your delivery time?
A: Usually 30-45 days after confirmation of all details and receipt of down payment if no valves in stock.
Q: How do you guarantee the quality of the products?
A: Our factory have strictly controlled the product quality. 100% testing from raw material, production to finished products. Any clients also can depute the third party professional institutions come to our factory to test the valves before shipment.
Q: How can I get the quotation of the project?
A: We will quote based on your drawing and other detailed specification if you have. Otherwise we offer our proposal for your confirmation then quote.
