High Pressure Ball Valves

发布时间:2006/01/26 OLIVER 仪表球阀 浏览次数:2143

The 'B6' Type Single Isolating High Pressure Ball Valve is designed for safe and reliable isolation giving bubble tight shut off. Totally enclosed soft seats offer both positive sealing and low operating torques, from vacuum to high pressure service. The anti-blow out spindle is fitted as standard with the option of PTFE or graphite foil seals. Recommended for use in the Oil, Gas and Petrochemical industries.

Overview

Our High Pressure Ball Valves are offered in three different configurations, namely: Integral Compression Ends, Threaded Ends Female x Female and Threaded Ends Male x Female.

As with our low pressure ball valves, our High Pressure Ball Valves offer totally enclosed soft seating, which gives the valve a positive sealing, and low operating torques across the whole pressure range. Unlike our low pressure ball valves, our High Pressure Ball Valves are capable of withstanding PSI ratings up to 10,000 PSI, and are recommended for use in the Oil, Gas and Petrochemical industries.

With a one-piece spindle with anti-blow shoulder, our High Pressure Ball Valves maintain seal integrity throughout the pressure ranges. We are also able to work with customers to provide High Pressure Ball Valves with increased body integrity through either PTFE or Graphite Foil spindle and body seals.

The handle found on our High Pressure Ball Valves is manufactured using 316 stainless steel, fitting with twin anti-vibration locknuts.

3D Models are available upon request.

Product Features

ADVANCED LOW TORQUE DESIGN

Our ball valves have very low operating torques, and a range of seat materials to give the ultimate in process environ mental compatibility.

STAINLESS STEEL HANDLE

One piece stamped 316 Stainless Steel handle gives positive feel, quarter turn rust-free operation.

STOP PIN

A 316 Stainless Steel "dead stop" pin is held into the body by a machined anti-vibration spline.

SEATS

Our totally enclosed seats offer wide process compatibility whilst maintaining a positive sealing across the entire operating range. This high level of seat integrity allows both vacuum, and high pressure services from one ball valve.

FIRESAFE SEATS

This option, in the event of a fire, ensures the ball/seat metal to metal contact is maintained. Note that the body and stem seals are changed to graphite.

BALL

This precision machined component is super finished assuring low operating torques.

FULL FLOW

Positive 90 degree travel combined with clear thru' bores, review table for full or reduced bore.

PROCESS THREADS

CNC super finished screw cut threads ease assembly with reduced risk of galling.

SPINDLE

A one piece stem incorporates an anti-blowout shoulder which maintains seal integrity at all pressures. Twin anti-vibration lock nuts are standard.

BODY SEALS

Totally contained PTFE 'O' ring body seals give high body integrity, and additionally protect the body threads from process media.
