| HAM-LET H700 BALL VALVES WITH LOCKING DEVICE |
|
The H700 Series is a moderate pressure instrumentation ball valve for general service and instrumentation panels.
The valves offer compact size of structure with relatively large ports, for high flow, tight shut-off, long life service and low operating torque. The H700 Series can be used for bi-directional flow and is rated to max. 2000 psig (135 Bar) and performs on-off service.
Features:
- Compliance with OSHA LOTO Standard 29 CFR Part 1910.147- Control of Hazardous Energy.
- Explosion Proof Stem*
- Vented Ball*
- Stainless Steel and Brass Construction. A351 or 316 Bar
- Welded end * (One piece body)
- Locking Handle in On and Off positions.
- MAWP 2000 psi (135Bar)
- MAWT 400°F (204°C)
- Flow coefficient (Cv) 1.25 to 17.35
- Size range: 1/4" to 1" or 6mm to 25mm.
*Optional

SEAT MATERIAL CHARACTERISTICS
RPTFE (15% Glass Fiber Filled PTFE) - Color (Off White) Short stand glass fibers are used as a reinforcement in valve seats. Adding reinforcements increases the pressure containing properties of PTFE by reducing its tendency to cold flow.
TFM®1600 - (PFA and PTFE composite) - Color (Bright White) Excellent seat material for purity applications, very low residual material during operation. It has lower deformation ratio than PTFE, but higher pressure and temperature rating than PTFE. Chemical resistance is equal to PTFE material.
|
PACKING ADJUSTMENT
Due to the varied service applications of the valve, packing adjustment may be occasionally necessary. Packing is factory adjusted to 1000 psig service. Initial packing adjustment is recommended after installation and prior to start-up. Please find more information at H700 under installation instruction. HAM-LET Ball Valves are designed to be operated in the fully closed or fully open position.
