One Piece Stainless Steel Ball Valve – Reduced Port, 316, 1000 WOG, PT/NPT/PF, 1/4″–3″ (R-1B)

وصف المنتج

A one piece stainless steel ball valve مُصنَّف 1000 WOG, with the body cast as a single piece and welded closed. 316 (CF8M) is the stock material; 304 (CF8) is made to order. PTFE seats, manual quarter-turn lever, reduced port, −20 °C to +180 °C. Two end builds: أنثى × أنثى (F×F) من 1/4 بوصة إلى 3 بوصات، و ذكر × أنثى (M×F) بأحجام 1/4 بوصة و3/8 بوصة و1/2 بوصة.

Because the body is one piece instead of two or three bolted or screwed sections, there is no body joint — one fewer place for the valve to leak. The trade-off is honest: it cannot be opened for service, and the bore is one pipe size smaller than the line. We say so plainly further down, and we point you at the valve you should buy instead.

ما الذي تعنيه عبارة «1000 WOG» فعليًّا؟

WOG تُشير إلى المياه، النفط، الغاز. إن تصنيف 1000 WOG يعني أن الصمام مصمم لتحمل ضغط تشغيل بارد غير صدمي يبلغ 1000 psi on those media.

Three things buyers get wrong about it:

• WOG هو تصنيف للبرودة. It is not a steam rating. This valve runs from −20 °C to +180 °C, set by the PTFE seats — tell us your line temperature and we will confirm it suits.
• “يُعد مصطلح ”غير صادم» جزءًا من التصنيف. في حالة حدوث ضربة مائية أو بدء تشغيل المضخة بسرعة، تشهد خطوط الأنابيب ارتفاعات مفاجئة في الضغط تتجاوز بكثير ضغط التشغيل العادي. يجب تحديد الحجم بناءً على حجم الارتفاع المفاجئ في الضغط، وليس على قراءة مقياس الضغط.
• On this valve, “gas” means compressed air. Fuel gas lines (natural gas, propane) call for a gas-listed valve, and this is not one.

إذا كان الضغط في خط الأنابيب الخاص بك يتجاوز 1000 psi في حالة البرودة، فهذا الصمام غير مناسب — أخبرنا بالضغط وسنقدم لك عرض أسعار للصمام المناسب.

F×F أم M×F — أيهما تحتاج؟

• أنثى × أنثى (F×F) — يتصل كلا الطرفين بأنبوب أو وصلة ذكورية. الخيار العام، وهو الخيار الوحيد المتاح لأحجام تزيد عن 1/2 بوصة (حتى 3 بوصات).
• ذكر × أنثى (M×F) — one male end screws straight into a female port, so you save a fitting and shorten the assembly. Available in 1/4″, 3/8″ and 1/2″ only. If you need M×F above 1/2″, see the two-piece MxF ball valve (1/2″–2″, full port).

Dimensions for both builds are on the PDF dimension sheets at the top of this page.

التطبيقات

A reduced-port, non-serviceable body is a deliberate trade: the smallest envelope and the fewest joints of the three ball valve body types, at the lowest cost of the three. It belongs where those three things matter more than full flow or in-line repair.

• Instrument and gauge line isolation — the shut-off ahead of a pressure gauge or transmitter, so the instrument can be changed without draining the line. Open it slowly; this is an isolation valve, not a throttling one.
• OEM machinery and skid-mounted systems — small-bore utility shut-offs built into a machine frame or a packaged skid, where the valve is replaced as a unit rather than rebuilt in place.
• التركيبات الضيقة — panels, cabinets and pipe runs where a two-piece or three-piece body will not fit. With no mid-body joint there is nothing to add length to the body.
• Compressed air branch isolation — take-offs from a plant air header to a machine, a filter-regulator or a blow-down point.
• Water and oil utility lines — general shut-off on cooling water, wash-down, lubrication and fuel-oil transfer lines up to 1000 psi cold.

Not for pump suction lines (use a full-port valve), fuel gas, steam, potable water or oxygen service — see the table above.

الأسئلة الشائعة

What is a one piece stainless steel ball valve?

A ball valve whose body is cast as a single piece and welded closed, instead of being bolted or screwed together from two or three sections. There is no body joint, so there is one fewer place for a line to weep. The trade-off is that the valve cannot be opened for service and the port is reduced — the bore is one pipe size smaller than the line. If you want the same no-body-joint construction with a full-port bore, see the seal-welded two-piece ball valve (V-2B / V-2C).

ماذا يعني 1000 WOG؟

WOG stands for Water, Oil, Gas. A 1000 WOG rating means the valve is rated for 1000 psi of cold, non-shock working pressure on those media. It is not a steam rating. On this valve “gas” means compressed air — it is not listed for fuel gas.

ما هو نطاق درجة حرارة التشغيل؟

−20 °C to +180 °C, set by the PTFE seats. Tell us your line temperature and we will confirm the valve suits it.

ما هي المقاسات المتوفرة؟

Female × female (F×F) from 1/4″ to 3″ — 1/4″ to 2″ as standard, 2-1/2″ and 3″ on request. Male × female (M×F) in 1/4″, 3/8″ and 1/2″. Dimensions are on the two PDF dimension sheets at the top of this page.

ما هي معايير الخيوط التي توفرونها؟

PT (تaper) هو النوع القياسي من الخيوط؛ كما تتوفر أنواع NPT وPF في المخزون.

316 or 304 — which should I order?

316 (CF8M) is the stock material and the one to choose wherever chlorides are present: brine, seawater, coastal air, most chemical service. The molybdenum in 316 is what resists chloride pitting. 304 (CF8) is made to order for general water, air and oil duty.

هل يمكن فتح هذا الصمام للتنظيف أو الإصلاح؟

No. The body is welded, so it cannot be taken apart. That is the trade-off for having no threaded body joint to leak. If you need to service the valve in line, buy the صمام كروي ثلاثي القطع instead. If you only need full-port flow and still want no threaded body joint, the seal-welded two-piece ball valve (V-2B / V-2C) is the one to look at.

هل هذا صمام منفذ كامل؟

No. It is a reduced (standard) port valve — the bore is smaller than the pipe. If you need full bore flow, buy the seal-welded two-piece ball valve.

هل يمكنني تركيب مشغل عليه؟

No. This body has no actuator mounting pad. If you need automation, buy the one-piece pneumatic ball valve, which has the ISO 5211 pad cast into the body.

هل يمكنك تقديم شهادة مواصفات المواد؟

نعم. يمكن الحصول على شهادة المصنع عند الطلب.
