Designed for higher class (class 3600) applications using high alloy or stainless steels

SEMPELL HIGH PRESSURE STOP VALVESMODEL VA510 (ASME)

FEATURES

• T-pattern globe type• Body made of forged steel• Wear resistant stellite body seat• Conical seat with line contact sealing• Visual position indicator• Non-rising hand wheel• Prepared for later automation in service• Low pressure loss due to optimized flow path• Small driving forces• Easy maintenance• Code compliance with ASME B16.34 and PED

GENERAL APPLICATIONS

These valves are designed for high pressure applications in conventional power plants. Applications include - vents, drains, bypass systems, warm-up lines, etc. wherever reliable leak tight performance is required.

SEMPELL HIGH PRESSURE STOP VALVESMODEL VA510 (ASME)

Large non-rising handwheel for easy operation.

Equipped with a mounting flange acc. to ISO 5210. No additional adaptor needed. An electric actuator can be mounted during operation easily.

Visual position indicator. Clearly indicates valve position at all times.

One-piece, non-rotating stem made of 17% Cr steel to ensure long life time of packing and easy mounting of a multi-turn actuator without changing any parts.

Bonnet is not a pressure retaining part and has no contact to the media, no additional cover sealing is needed.

Valve body made from bar material allowing a wide variety of materials to be used – including special materials acc. to customer’s requirements.

Low pressure loss due to optimized flow path and large channel borings.

Capsuled valve yoke for protection against environmental influences.Cup springs allowing the compensation of thermal stem extension to keep the valve closed even at variations in temperature.

Low friction roller bearings for small driving forces.

Capsuled valve yoke for protection against environmental influences.

Stripper-ring sealing of packing protects the stem/packing area against dirt and avoids leakage.

Two-piece gland for quick disassembly and repacking.

Pure graphite packing with non-extrusion ring prevents packing migration and ensure long service life.

Sufficiency long cylindrical connections for heat treatment and UT- testing.

Conical disc with line contact sealing for a defined seating for a tight shut-off.

Wear resistant stellite seat ring welded and repairable. A special tool kit for lapping the seat is available.
